@@ronevans3027 Depends on what you want. These guys are just rallying around Banks because of a bash video he published a while ago. With some very shaky reasoning on alot of his decisions.
Good thing you and your product testing and engineering skills were put to use on the Banks testing team and then be able to tell us what actually went on after the cameras were turned off.
@@stradplayer90 Shaky reasoning? He showed very clearly (literally caused they used lexan to see inside the cover) how the shape of the cover affects the oil circulation. These squared off covers screw up the oil flow, not allowing enough oil to get to the pinion bearing.
Granted in the Banks videos that there was a lot of oil coming up the flat side of the aftermarket cover but that doesn't mean that no oil was getting to the pinion, I'm sure the pinion gear was getting plenty of oil and you just couldn't see it because there were no cameras back there to show it. Also he talked about aeration and I saw more bubbles from the stock cover than the aftermarket cover. One other thing is he talked about the temperature on the aftermarket covers being higher than the stock cover yet he never gave any temperature numbers on any of the aftermarket covers! In the very end he talked about them making a cover and it looks like it will be rounded and it seems to me he wants to discredit the flat back cover so that when his rounded cover goes into production people will think it's better but that's just my opinion!
Sixteen years ago I put a “flat” Mag Hytec cover on my new 2003 Dodge Ram 2500. Towed toy haulers, travel trailers, you name it. Living in Southern California steep mountain grades are everywhere. I ran good quality synthetic gear lube. 300,000 miles later, not a single problem. Banks is a master salesman. If your only experience with the “flat” differential covers is the Banks videos I’m going to discount your opinion, nothing personal. If flat differential covers were really a problem this post would be full of guys complaining about the longevity or lack thereof of their pinion gears don’t you think. Those videos without the sales pitch don’t show anything but fluid moving around in the differential housing. Which is what you should see. And still no part three video? I put the Mag Hytec on for the drain plug and fill hole which reduces maintenance time and it looks nice.
Yep, yep these manufacturers failed to do basic form and function research. These products change the fluid flow, which increases temperature, loss of power and most likely damage to the differential over time.
@@lordwoe1787 well this didn't age very well. Temperatures are LOWER than stock! "loss of power" is extremely negligible. Know of anyone with them that has had damage to the differential over time? Neither do I... Gale Banks sure is a great salesman! Well, for the mindless like yourself.
@@internetcrap7 it's typical banks Bs.. In There own comparison they admitted a substantial temperature drop on the mag- hytec. Gear oil is made to operate at extremely high temps so the ram air scoop is redundant. 😂. All these people who claim that these are bad have no engineering background. If the ram air scoop was so effective then Why wouldn't manufactures put them on?...... Snake oil. I know somone who has put 200,000 miles on a mag hytec diff cover and has had no problems which proves it's literally bullshit.
Truck nuts don't damage your truck. Differential cover that prevents the ring gear from carrying lubricating oil to the pinion bearing provides negative value. Negative as in you will be paying to have your truck towed and the dry running broken pinion bearing changed.
Thank you Gail Banks for proving that these increase temps, decrease mpg, thus making it a total waste of money. And these covers may even be dangerous to run.
Banks has yet to reveal his test data, I am very interested in seeing if the increased surface area of these aftermarket covers outweighs the benefit of the smaller channeled cover. What banks video failed to emphasize is that a gear will carry fluid through the housing regardless of the back cover channel. while the stock design helps fluid circulate, and helps cooling flow, does the increased capacity and surface area combined with the lesser but still carried fluid by the gear alone result in overall better cooling. my personal observation is that the stock channeled cover circulates a lot more fluid than needed to the axle shafts for the reason that many people do not check the rear end fluid levels sometimes and often for the entirety of the vehicles life. its more of a security feature for low fluid levels than an actual be all, and end all design advantage. i could be way off but, I wont write off these aftermarket designs just yet.
Well put. Your saying what I’m thinking. Banks never finish the test video. I went with the mag hi tech for the dip stick and drain plug on a 2001 Ram 2500 H O. After a year and a half from factory the oil drained out black. Next hypiod charge was November 2020. It was was only moderately darker than new oil. Through the years I added very little oil and the magnet had very small amounts of metal. The axle seals are still good so I’m very happy. Hypiod gear oil stinks anyway but the used oil never smelled burned. Mr Banks give us your results. As for now I’m assuming it isn’t as big a deal as you market it to be. I should mention the Ram has 187,000 miles. It’s not a daily drive but the camper and trailer with the SxS make for a heavy enough load.
More is better but not here more fluid doesn't mean faster cooling been proven many times and also just waiting the part 3 of the banks video to see actual results plus the inside design of these aftermarket diffs r flawed but sadly I believe even after banks proves how these things r just bling the prices most likley won't change they're gonna be lots of people still buying them and paying the same price they r now
Exactly. More fluid doesn't mean faster cooling, it means slower heating. Slower heating is NOT desirable because it takes longer to reach operating temperature, and cold oil doesn't lubricate as well and increases drag longer.
PRSH8YA stuff they always fail to mention that in these types of promo videos. You'll end up with condensation and then water contamination in no time.
i'm not a truck owner nor interested in these, but isnt it better for the diff if it takes longer time for the fluid to heat up? Also they have some serious cooling fins as well which OEM does not.
@@FrenchValleyAirport that makes sense but no one has studied it yet, except for banks who is currently in research on this. But remember once hot it stays hot longer
do you really need all this? think not. i have 420k on my dmax and over 600k on my ram with out never applying parts like this. always changed oil. always pulling heavy loads zero problems. dont waist your money
1Slamalama1 nothing wrong with having a diesel truck used to tow that is tuned 🤷🏻♂️ makes towing easier with more power. That’s why they make tow tunes. And it adds for more fun.
Tryin2fly09 so people can’t have their own opinions and do what they want to their own personal vehicle? Also no need to get racist with the slur. I know plenty of people with lowered “street trucks” that tow more than most. Yes they’re made for pullin so why not do what you want? Can’t tow in silence so why not bump to some “lil Jon” even tho he hasn’t released a good song in god knows how long.
David Ciesielski haha very true why get a aftermarket diff cover for more oil and better cooling when you can rock the stock one that is rusted over 🤷🏻♂️😂
I have used the Mag Hytec cover on at least 10 of our trucks. We have never had any bearing or gear problems. We also change the fluid every 30k. The cover makes servicing very easy. Plus it looks good.
Hi Thoroughbred Diesel, I appreciate you uploading this video but I have to concur with "Drwinlied's" comments; there is no recommendation as such for what cover to use (which is what your video title states). What I see is a presentation of what is/was available (back in 2014) but no other useful information. Ford, Ford/Sterling, Dana manufacturers have designed their covers for specific specific engineering reasons - your description of these covers does not address any "pros or cons" of these covers other than the "look" i.e. this video is purely "descriptive". The OEM shape of differential covers/casing is dictated by lubrication distribution especially on high usage differentials such as "muscle cars" and heavier duty trucks. I do not see any advantages in the covers you presented other than convenience of checking the differential oil level (loss of differential oil is a very rare occurrence in real life, non-racing applications). I would recommend reviewing the dynamics of differential lubrication/oil flow and/or renaming your video. Ciao, L (FoMoCo engineer).
I think everyone should check out the FordF450 rear end cover. This cover is stock from the factory. I believe its manufactured by Dana, Whether its a requested by Ford or its a design feature by Dana. So the overall conclusion of this comment about Ribs and Aluminum construction is that BANKS can't be blowing smoke here, Its not just BANKS believing this is BETTER for reliability .
allen wrench toi keep from stripping out? what the hell is he talking about! why the hell cant they just put male plug instead of the recessed extension style plug? every vehicle ive changed the diff fluid on i threw away the extnesion style plug and went and got a male plug so i can put a wrench on it way better than anything else.
I love how everybody likes to use the terminology aircraft aluminum. Well I'm in the industry and I've never seen aircraft-grade cast aluminum. What a joke. Not to mention the fact that is not rounded inside for the fluid to get pushed over the ring gear and into the holes lubricating the pinion bearings well. This is a great gift cover for guys with small man syndrome driving huge trucks but never get them dirty
Reminds me of commercials advertising Military Grade "anything". Military grade sounds awesome until you are actually in the forces....then it sounds terrifying.
The only thing that, "aircraft grade" means is that the material supplied is what was on the aircraft part manufacturer's purchase order, and that there are material certs to verify that.
But main question for the purpose of buying one of those covers is do they Really lower the diff lube temp Diff covers have been designed for years by all the manufacturers a cover that is shaped like the internal shape of the ring gear and carrier that directs to lube to the front of the pinion None of those do that you mean the oems have been doing the shape wrong Even heavy duty trucks shape their housings in a more form fitting shape not like a pot 190,000 on my dana 70 stock rear axle With the extended amount of gear oil and price of cover you can change your oil more often
Should have mentioned that the ones with a brace on top can't mount your brake line. I had serious trouble with steel pans leaking because they bend where bolt holes are and won't create enough force in between the bolt holes to crush the gasket. After switching to a solid aluminum I have never had a leak since. The cooling, looks and structure are just a bonus. Can't stand leaks.
You show how pretty those covers are but how does the fluid flow on inside? that is your differential fluid get around your axle gear? this is not a very informed video you need to do more investigation before you put out a video
I have a 2007 Lincoln Mark LT and I have the mag-hytec rear diff cover and transmission pan both on my truck. Whether or not the rear differential cover is just "bling" or not, I am glad I installed one if not just for the sole purpose of having a drain plug built into it making changing the fluid a whole lot easier.
Ok, I'm no expert, while doing some research on engine oil, is it dirty or worn out? I came across information that said something like this, if the oil is down 1 quart the oil temp raises alot, so I'm thinking as cool as these covers look, the thinking may be the more gear lube inside, the lower the temperature inside. Banks seems to pointing out the gear lube is not properly directed to components inside the diff. I have no stake in this my diff has the stock cover.
Does not cover how it impacts the lubricity process of the lubricant flow. Stock covers are domed and allow for uninterrupted flow of axle lubricant when the gears are spinning. What effects do the flattened covers have on the fluid flow? Anyone using these do a study to see if they have a negative impact on the process?
Yeah this video was produced long before Banks came out with one. If you care to do a bit more research you will find our review of Bank's diff cover on our channel as well.....
I know that my truck isn't a diesel, or a pickup truck. Do you guys offer any diff covers that would fit a 01 Durango with a 9.25 rear and 8" front diff?
None of these are any good. Square backs equals aeration equals poor lubrication equals high temps. Plus stainless steel hardware is no good. Customers will find themselves with broken bolts in the hole if they ever have to remove/reinstall the cover. Stainless bolts are prone to galling which will seize the bolt in the hole, causing it to snap off. The the only option then is to drill it out because you can't remove a galled bolt with a bolt extractor. It's basically friction welded in.
Banks destroyed those brands with solid engineering and testing. I wouldn’t buy an aftermarket diff cover anyways since stock is more than adequate, but if I did it would be Banks.
Huge waste of money! Let me see who I’m going to trust, some aftermarket company or an axle manufacturer/auto company with millions in R&D invested🤔 The Gail Banks study has confirmed suspicions I’ve had for years. The data he has collected is truly impressive and already shows these covers are inhibiting the intended operation from a lubrication standpoint. Can’t wait to see the final conclusions from next installment
Have a flat back with a stock like design inside . Banks will only make these companies have to make them function better. Only prob is I bet the price goes up more then double. Gonna be $799.00 I bet
While I appreciate at least the overview you provided to these parts, not a lot of useful information on performance. Especially for a title that states, "not just bling" there was literally no factual information provided to prove these aftermarket covers were not, in fact, just bling. Design and actual function of design are certainly both worth a look. Does the Mag-Hytec not having the heat fins cast through the inner portion of the unit make an actual difference? Who knows, we certainly aren't finding out in this video. That likely comes off more disgruntled than I really am, but I was hoping to learn useful information and not a single thing was tested in any way.
Did anyone ever test ones with internal fins to see how much they affected temp.or is it just a selling point and wouldn't bare polished aluminum transfer heat the best.
Go Ahead Make Our Day Scooter &Peanut external fins will dissipate heat faster than flat surface. The more surface area that us exposed to cooler temperatures the faster the heat can be wicked away. Fins on the inside would only transfer heat to the cover faster than necessary since the heat cannot be wicked off the cover as fast or faster.
What is the normal operating temperature of a rear differential on a Ford , Dodge or GMC? If I'm towing within the limits of my truck why do I necessarily need this cover? Who has proof of these making a difference between OEM & aftermarket ?
Johnny Koch I'm going with that as well. Only question I have is the fill lines. The stock level check right in the middle is lower than the lowest line on the dipstick. Any idea why? Do you fill it until it drains from that hole or go strictly by the dipstick?
Have you installed the AFE cover on a 2015 2500HD (GMC Sierra Denali Diesel) 46-70012. If so, do the factory cable/brake line mounts work without modification or does AFE include adapters for them in the kit?
Thanks, Thoroughbred, for a good video, but is Thoroughbred showing us the covers they sell? Because I'd like their take on the Banks diff cover too? It has been designed to distribute the oil differently and air cooled as well. Check out this video th-cam.com/video/9-yG3D3JBRs/w-d-xo.html. This video shows you what is going on under the diff cover as it works. It shows what the aftermarket guys are not showing us. Let's hear it. Thanks
I was looking at going ATS, I love the look. But I see the AFE has all the brackets for the brake lines. Does the ATS also have this, if not how do we hook the lines up? Thank you
higher resistance will raise the temp, imagine moving your hand in a pool vs out the pool, the waste of energy needed to move the water will be directly transfer in heat
For the ’14 to present trucks with the coil springs, you will need part number AA 14-11.5 CS found here: www.thoroughbreddiesel.com/2014-dodge-ram-2500/aa14-11-5cs/
I appreciate Thoroughbred taking the time to make the video but it would have been much better if the script was planned ahead. This guy was not good with off the cuff talking. I could hardly make out what he said in the beginning and he really didn't have much to say about the the comparisons of each cover either. I learned nothing here but maybe saved myself a couple minutes or researching each manufactures website.
Midwest Bodybuilding Heat kills parts. Parts are expensive to purchase and install. If you tow or haul a lot with your truck on a regular basis the added lubrication, ease of service and cooling properties of these covers will help your axels and differential last much longer. Some of these covers lower your rear end temperatures by 45-degrees! They aren't cheap, but if you've ever had to replace axels or differentials, these covers are a sound investment.
Well, no. Not just more fluid, but added cooling capacity as well. It's like 2 kids in a kiddie pool, it will get filthy pretty quickly. Same 2 kids in an olympic size pool, swim all day, pool looks the same. Same with oil. More oil won't contaminate as quickly, and has the added benefit of spreading the heat around over a larger volume. Cooling fins both inside and out are a larger surface area to transfer heat away from the oil, keeping it cooler. And aluminum transfers heat better than stamped steel, so it's win-win. I've seen stock, painted covers where the paint is burned off at the oil line where it heat soaks after shutdown. More oil and cast aluminum are practically a requirement for towing heavy if you want a rear end to last. My best guess is CaptP above has tow mirrors out, and runs a smoke tune, and is living in a fantasy world. 600k on a RAM.... now that's funny right there.
I own a banks cover and to be honest they are all hype and a great sales pitch. Also the flat back covers look a lot better than the stupid banks air scoops. Never mind the price tag, I could have gotten a BD Diesel front and back cover for cheaper than the Banks.
@@thoroughbreddiesel Haha I try to be positive, but sometimes you get those dang I shouldn't have fallen for it moments. Have you guys made a newer video with the banks cover?
Spicer does not recommend these aftermarket pans as they starve the pinion gear of oil and cause premature failure, My 99 had one, and the pinion bearing and carrier were destroyed due to lack of oil, there are aftermarket pans that look like these featured but they duplicate the inside of the stock pan, buyer beware, also more oil does not = better.

Very informative video, well done.
I love the look of the ATS, but the AFE cover has all the bells and whistles
People:What's the better diff cover?
Gale Banks: mine!
None of the above!
Nice way to ride the banks wave
But main question for the purpose of buying one of those covers is do they
Really lower the diff lube temp
Diff covers have been designed for years by all the manufacturers a cover that is shaped like the internal shape of the ring gear and carrier that directs to lube to the front of the pinion
None of those do that you mean the oems have been doing the shape wrong
Even heavy duty trucks shape their housings in a more form fitting shape not like a pot
190,000 on my dana 70 stock rear axle
With the extended amount of gear oil and price of cover you can change your oil more often
All of these are badly designed, stick with the stamped steel cover.
Should have mentioned that the ones with a brace on top can't mount your brake line. I had serious trouble with steel pans leaking because they bend where bolt holes are and won't create enough force in between the bolt holes to crush the gasket. After switching to a solid aluminum I have never had a leak since. The cooling, looks and structure are just a bonus. Can't stand leaks.
I like the AFE cover the best, think that's what I'm going to go with on my 02 7.3L F-350 Powerstroke
Save your money. Watch Gail Banks’ videos on these covers.
You show how pretty those covers are but how does the fluid flow on inside? that is your differential fluid get around your axle gear? this is not a very informed video you need to do more investigation before you put out a video
The only thing the cover is gonna do is look cool keep your OE cover and save your diff
Due to Mr. Banks' efforts, this video has not aged well. The dislikes are clearly from the companies made obsolete by science. Awkward.....
I have a 2007 Lincoln Mark LT and I have the mag-hytec rear diff cover and transmission pan both on my truck. Whether or not the rear differential cover is just "bling" or not, I am glad I installed one if not just for the sole purpose of having a drain plug built into it making changing the fluid a whole lot easier.
for a ford excursion 7.3 2wd what would you recommend?
These companies did no research whatsoever unlike Gale Banks.The entire description is 100% wrong.Once again check out Banks.
Ok, I'm no expert, while doing some research on engine oil, is it dirty or worn out? I came across information that said something like this, if the oil is down 1 quart the oil temp raises alot, so I'm thinking as cool as these covers look, the thinking may be the more gear lube inside, the lower the temperature inside.
Banks seems to pointing out the gear lube is not properly directed to components inside the diff. I have no stake in this my diff has the stock cover.
Does not cover how it impacts the lubricity process of the lubricant flow. Stock covers are domed and allow for uninterrupted flow of axle lubricant when the gears are spinning. What effects do the flattened covers have on the fluid flow? Anyone using these do a study to see if they have a negative impact on the process?
Banks should build these so they work correctly
Not smarter than the OEM engineers
Banks are the best
I have a question guys.
Which one is the best. 1999 Ford F350 Dually, with a wedge trailer for 3 cars, I'm a car hauler OTR ) thanks
Mag hytek. O ring seal and fill plug on top. Holds 2 gallons.
I see Mr. Gale Banks is not mentioned in your ADVERTISEMENT....
GO AHEAD......RUIN YOUR AXLE.
Yeah this video was produced long before Banks came out with one. If you care to do a bit more research you will find our review of Bank's diff cover on our channel as well.....
I didn't know diff covers were a thing
My AFE cover has leaked from day 1
May be the gasket.
Bling and no zing? What is the point? Vanity?
Mister Berzins same as many of the tire/rim combos.
I know that my truck isn't a diesel, or a pickup truck. Do you guys offer any diff covers that would fit a 01 Durango with a 9.25 rear and 8" front diff?
None of these are any good. Square backs equals aeration equals poor lubrication equals high temps. Plus stainless steel hardware is no good. Customers will find themselves with broken bolts in the hole if they ever have to remove/reinstall the cover. Stainless bolts are prone to galling which will seize the bolt in the hole, causing it to snap off. The the only option then is to drill it out because you can't remove a galled bolt with a bolt extractor. It's basically friction welded in.
Gale Banks is showing us why they may or may not be useless.
All you guys act like experts after watching banks video!!
Spicer is the proper site to go, they make the freakin diffs, they should know.
Banks destroyed those brands with solid engineering and testing. I wouldn’t buy an aftermarket diff cover anyways since stock is more than adequate, but if I did it would be Banks.
Huge waste of money! Let me see who I’m going to trust, some aftermarket company or an axle manufacturer/auto company with millions in R&D invested🤔 The Gail Banks study has confirmed suspicions I’ve had for years. The data he has collected is truly impressive and already shows these covers are inhibiting the intended operation from a lubrication standpoint. Can’t wait to see the final conclusions from next installment
Have a flat back with a stock like design inside . Banks will only make these companies have to make them function better. Only prob is I bet the price goes up more then double. Gonna be $799.00 I bet
Everybody is WOKE after watching Gail Banks!! Don’t waste your money!!
I don't know...…..if they are all just BLING, why is Banks investing so much time and money to develop his own?
Good Stuff,Great Tips😄👍🏿
Thanks!
What about specs for our f350
While I appreciate at least the overview you provided to these parts, not a lot of useful information on performance. Especially for a title that states, "not just bling" there was literally no factual information provided to prove these aftermarket covers were not, in fact, just bling. Design and actual function of design are certainly both worth a look. Does the Mag-Hytec not having the heat fins cast through the inner portion of the unit make an actual difference? Who knows, we certainly aren't finding out in this video.
That likely comes off more disgruntled than I really am, but I was hoping to learn useful information and not a single thing was tested in any way.
We updated the title to be more reflective of the content.
went with afe front and rear f250
There all a waste of money
will that afe fit my hummer h2 ?
Did anyone ever test ones with internal fins to see how much they affected temp.or is it just a selling point and wouldn't bare polished aluminum transfer heat the best.
Go Ahead Make Our Day Scooter &Peanut external fins will dissipate heat faster than flat surface. The more surface area that us exposed to cooler temperatures the faster the heat can be wicked away.
Fins on the inside would only transfer heat to the cover faster than necessary since the heat cannot be wicked off the cover as fast or faster.
What is the normal operating temperature of a rear differential on a Ford , Dodge or GMC? If I'm towing within the limits of my truck why do I necessarily need this cover? Who has proof of these making a difference between OEM & aftermarket ?
Mag hytec all day
Johnny Koch I'm going with that as well. Only question I have is the fill lines. The stock level check right in the middle is lower than the lowest line on the dipstick. Any idea why? Do you fill it until it drains from that hole or go strictly by the dipstick?
Have you installed the AFE cover on a 2015 2500HD (GMC Sierra Denali Diesel) 46-70012. If so, do the factory cable/brake line mounts work without modification or does AFE include adapters for them in the kit?
this just made my decision harder between afe and mag lol
Mag has a better o ring seal
You forgot to mention that the aFe diff cover also has cooling fins on the inside of it
Why do you put an awl in the differential?
I think we used that to align holes in the cover.
Thanks, Thoroughbred, for a good video, but is Thoroughbred showing us the covers they sell? Because I'd like their take on the Banks diff cover too? It has been designed to distribute the oil differently and air cooled as well. Check out this video th-cam.com/video/9-yG3D3JBRs/w-d-xo.html. This video shows you what is going on under the diff cover as it works. It shows what the aftermarket guys are not showing us. Let's hear it. Thanks
This video was long before the Banks diff cover came out.
I was looking at going ATS, I love the look. But I see the AFE has all the brackets for the brake lines. Does the ATS also have this, if not how do we hook the lines up? Thank you
Are these pans only for diesel trucks?
We offer pans for gas applications as well.
Thoroughbred Diesel great! Any for 2006 Dodge Ram 1500 with 4.7l engine?
The Mag-Hitec on our chevy 3/4 ton 5.7 has worked out great. Looks cool too.
does anyone make one for 2015 Silverado 1500?
Thanks! Went with AFE front and rear!!
what type of gear oil and friction modifier are recommend???
“Increased oil capacity means increased cooling capacity” if that’s the case, then why not fill it full?
it will overheat
and pop seals
“It will overheat” lol! So increased oil capacity doesn’t mean increased cooling then
higher resistance will raise the temp, imagine moving your hand in a pool vs out the pool, the waste of energy needed to move the water will be directly transfer in heat
TD you need a redo here.... ;)
Possible. This video is many years old at this point.
Mag hytec all day!
If you take a cover off to replace fluid and check inside the diff that has an O ring seal do you need to change the O ring?
Some of the aftermarket covers today have o-ring seals and yes, we would suggest changing it once you have reopened the diff.
Will any of these fit if you have rear coil springs?
Are you referring to the Dodge with the AAM axles?
Yes, I have 2016 ram 2500 and it has rear coil springs. So it has a sway bar going across the axle horizontal. And another bar just above the axle.
For the ’14 to present trucks with the coil springs, you will need part number AA 14-11.5 CS found here:
www.thoroughbreddiesel.com/2014-dodge-ram-2500/aa14-11-5cs/
I appreciate Thoroughbred taking the time to make the video but it would have been much better if the script was planned ahead. This guy was not good with off the cuff talking. I could hardly make out what he said in the beginning and he really didn't have much to say about the the comparisons of each cover either. I learned nothing here but maybe saved myself a couple minutes or researching each manufactures website.
Oil not awl.
Line not lahn.
Product not prodict.
What's oil?
Great video, big help in product description.
+Terry Bettes Thx!
such an inflated price for a simple cover. PURE profit. not one cent lost in the making.
hmm mag or BD
They all look like solid covers hard to get hurt with any of those.
Was ganna call bs but it seems im late to the party lol.
stock
Great video guys. I am going to get the AFE Cover for my Ram 2014 3500 crew cab Laramie.
You will regret that. Watch the banks power video showing how those work. It fucks up the fluid dynamics.
I can't justify the price. Why would I purchase this? Just to have more diff fluid?
Midwest Bodybuilding Heat kills parts. Parts are expensive to purchase and install. If you tow or haul a lot with your truck on a regular basis the added lubrication, ease of service and cooling properties of these covers will help your axels and differential last much longer. Some of these covers lower your rear end temperatures by 45-degrees! They aren't cheap, but if you've ever had to replace axels or differentials, these covers are a sound investment.
Well, no. Not just more fluid, but added cooling capacity as well. It's like 2 kids in a kiddie pool, it will get filthy pretty quickly. Same 2 kids in an olympic size pool, swim all day, pool looks the same.
Same with oil. More oil won't contaminate as quickly, and has the added benefit of spreading the heat around over a larger volume. Cooling fins both inside and out are a larger surface area to transfer heat away from the oil, keeping it cooler. And aluminum transfers heat better than stamped steel, so it's win-win. I've seen stock, painted covers where the paint is burned off at the oil line where it heat soaks after shutdown. More oil and cast aluminum are practically a requirement for towing heavy if you want a rear end to last.
My best guess is CaptP above has tow mirrors out, and runs a smoke tune, and is living in a fantasy world. 600k on a RAM.... now that's funny right there.
Great video, gents!
I own a banks cover and to be honest they are all hype and a great sales pitch. Also the flat back covers look a lot better than the stupid banks air scoops. Never mind the price tag, I could have gotten a BD Diesel front and back cover for cheaper than the Banks.
Thanks for the feedback. Always good to hear from customers even if it isn't positive.
@@thoroughbreddiesel Haha I try to be positive, but sometimes you get those dang I shouldn't have fallen for it moments. Have you guys made a newer video with the banks cover?
@@joker321s Not one comparing them all but we have two video up on the banks cover. Currently have it installed on my truck.

ATS all day!
Spicer does not recommend these aftermarket pans as they starve the pinion gear of oil and cause premature failure, My 99 had one, and the pinion bearing and carrier were destroyed due to lack of oil, there are aftermarket pans that look like these featured but they duplicate the inside of the stock pan, buyer beware, also more oil does not = better.
