300,000 views just before the New Year! Thank you!!
Thank you! I would be concerned about the forced but if one could be built strong enough, I bet it would be a great option.
Thank you for the in depth explanations I have a question, for drifting a locked differential is a must would one of your e lock differentials work for drifting because the slack would not affect a car being that you don't end up rolling backwards and my daily driver is also my drift car so this seems very practical because i don't want to weld my diff looks like a pain to daily drive
and would an ox locker work as well?
Do you offer a military discount? I'm interested in the OX locker (cable). I did look at the FAQ first.
Congrats! I have a question about the Detroit locker. For an F150 IFS, would it cause any problems when in 2wd? Would it potentially cause damage to the weaker IFS?
By far this is the most comprehensive yet simple explanation of different differentials. Thank you, Ben.
That's exactly what we were going for, thanks!
I know you did this years ago and you probably won't even write but man this was a great video I have a 1994 ford f150 4x4 with 4 inch lift and plan on doing 6 inch anyways after watching your Awesome video I believe I will be doing the (Spartan lockers) front and rear, I would like to do the Detroit lockers but I really dont have that kind of money and I looked up the Spartans lockers and similar ones like them through jegs and summet racing and they run around $320.00 give or take a couple 20.00,s
@@edwardkesock216 ...I'm scrolling through here thinking, "no point in commenting here, after all this time", but there you are. lol
What an interesting tutorial, and as someone else said "very professional" with no umms and arrs. I was soaking it all up. What a bloody good job. I wonder where this bloke is located.
I've bookmarked this video for future reference. Bloody awesome.
Great video. Thanks!
I knew nothing about diffs before this vid… now “i know king fu” - Neo
What a professional! No errrs n' aaarrrrs, no derailings, just perfect execution of message. Subscribed!
Thank you! Don't be too impressed, it took a lot of re-takes!
@@Filthymotorsports So cool of you to admit that. :)
@@Filthymotorsports At least you took the trouble.
LSD, "Small clutch pack, like you'd find in a manual transmission" ?? Might be one errrs
2:20 I detect an uhh.
I've come back to this video multiple times over a couple years. Amazing video.
So glad to hear it, thank you!
THE best off road differential description ever. This presentation doesn't go overboard with sponsor support. 100% mechanics, installation, application and engineering. AWESOME video. Thank you!
So glad you enjoyed it, thank you!
Had a Detroit style locker before in a light vehicle. Annoying to drive both on road and off road.
On road it was the worst if not being driven correctly.
It would lock in a tight turn if letting off a little on the gas or started to engine brake.
Needed to keep a certain amount of power or freewheel else it would lock up shaking and unsettling the car with screaming tires.
Off road one felt there was lot of play in the system when in rock or uneven terrain. Very jerky because the wheel has to turn a little before power would be transmitted in the opposite direction.
Every time the car would get over to the other side of a stone it would move an extra foot rolling before engine braking worked because of the huge slack in the system.
It worked best when driven "hard" because then it would always behave like a spool.
Very well explained, this comment needs more likes to bump to the top!
@@Filthymotorsports Alternatively, you can pin it. :)
This concerns me @Anders Sandkvist. I'm considering one now for cost and ease of use when I go 4WDing. Got a hilux dual cab. I also tow a camper trailer. Would you not recommend it?
Definitely a learning curve to a detroit
I have Lock-Rites (lunchbox/Detroit-style lockers) in both axles of my K10 and they've performed flawlessly for over six years. No learning curve, no clicks, no scrubbing, 99% transparent in daily street use. Perform in low-traction situations. Highly recommend. Only odd thing is that they cost as much a the Eaton Tru-Trac I installed in my Silverado.....
Finally understood how TOR SEN diffs work. Thank you.
So glad to hear it, that one is seriously tough to explain!
Yeah me too!
Well done, informative vid. I like the 'real world' addition of the welded spiders. In 50+ years, I have never seen anyone who makes money selling aftermarket parts be as real as that.
If I was still building toys that break parts, you'd have my biz. Good on ya'
So glad to hear it, thank you for that! Cheers!
I welded my buddies rear end in his chev 1500 that lasted about 2 months before his gears were shot. I also welded my Jeep Grand cherokee axel that lasted about a month before it blew up going down the highway. It was super fun though!
Still relevant and full of good info 6 years later. Thanks!
Absolutely. The only thing that has changed is that some Eaton E-locker models have changed to a positive engagement collar but only for larger axles. Thanks for watching!
I wish all TH-cam videos were this good. Heck, I wish any TH-cam videos were this good. Thanks, Ben.
That was probably the best explanation of differentials I have ever seen thank you!
This is by far the best discussion on this topic I've seen anywhere. Thanks for doing it.
Great video! Best explanation on TH-cam of what a locker is, the different types and how each works, and pros and cons of each.
Great video, really explained, especially for all us diy 4wheelers.Much appreciated keep up the good work.
Very thorough, thanks for sharing your knowledge!
Wow, thanks for making a great, informative video. Your channel deserves more subs!
Saved this video a good while back when I was hard looking for a non-open diff for my truck. Finally got around to watching it and you have earned at least a sub, like and comment. Great explanation on lockers and all their varying flavors! About to go check your website for inventory availability.
Just reached 200,000 views! Thank you all for the support and your feedback! We have more videos like this coming out soon so make sure to subscribe to our channel. Cheers!
This a very helpfull for offroaders like me! I'm from Brazil and here is difficult to chose the best solution, because it's no easy to have all options at hand before the purchase. I'm on my way to get a Eaton e-locker!
So glad to hear it, great choice!
Miata's are famous for Torsen diffs. I had a 2000 SE with 180k miles that would squall both rears off the line at autocross events for 2 plus years. still worked great when I sold it
Thank you Ben! I was sold on an Eaton e locker but after watching this video I am seriously considering an ox Locker now.
This is the BEST comparison/explanation of all similar videos on TH-cam
Bela explicação, muito obrigado!
Optei pelo e-Locker.
Thanks, that was the best explanation I've heard.
You did a great job explaining and really seem to know the products your selling. Based on this video, I would definitely give you my business!
Thank you. It was sooo nice to see everything laid out so clearly. Great information. If this is your channel (clearly explaining things in a fact based way) I'm subscribed.
Dude, my brain was growing and growing with each beaut of an explanation you gave and then right at the very end my brain exploded 🤯. So worth it tho, the fragments with come together as needed.
Thanks man 🤘
The best, most concise and clearly articulated presentation on this subject that I have ever seen. I’ll subscribe for more of this type of quality content.
now thats a video I am looking for..
GOOD JOB
Thank you!
Clear, informative, unpretentious and very helpful. Top notch. Thanks..
You are very good at explaining things mate, thanks for sharing this content!
Great Video! I sent an Email question to Ben. Excellent explanations. Almost like going back to trade school. Air Lockers where just coming on the scene but in the farm tractors we have had them for years at that point. The rest were being used in automotive applications
Love my Detroit Lockered Dana 60, it's got my old 3/4 ton 2wd in and out of places where open diff 4wd fear to tread. Decent street manners too.
I've been offroading for over 30 years, I have never seen a better explanation of different style traction devices!
So glad to hear it, that means a lot!
The best and most thorough explanation I've seen
Excellent video.....clear, concise, and easy to follow. Thanks for posting :)
I'm so glad to hear it, thank you for watching!
This is the best explanation on the tube. Gracias.
So glad you think so, thanks!
Agreed 1000%
Excellent video!
I have to agree, I had very little idea when I started looking for explanations, and this vid led me to choose the type.

Much agreed - very well put together video, didn't mind the 29 minute length one bit. I'd really like to see a video of vehicles out on a slippery hill demonstrating as many of these as possible, especially open vs torsen vs one of the selectable lockers vs detroit vs spool.
I understood all this but watched in its entirety just because it's so well presented. Thank you!
An excellent presentation! Using ARB lockers in my Ibex, but fascinating to see how the other variants work. Hope you have a good 2018.
fantastic video this is the best demonstration of the different differentials I've ever seen really really good video thank you for taking the time to do such a great job to educate the public five stars to you
Thank you! It took a lot of work to put together so the positive feedback is great to hear!
OUTSTANDING PRESENTATION BEN!
SUBSCRIBED!
THANKS!
Glad you like it! Cheers!
Agreed, Don. Subscribed here as well. Bravo Filthy Motorsports. Best presentation I've seen and I will return to reference this in the future as well.
Excellent detailed explanation of lockers and diffs.
Thanks for the upload. Excellent demonstration. 👍
great explanations... brilliant
Thank you! I'll have to check out your channel when I have time, we work with many customers in Australia!
Their channel is amazing!!
This is a really incredible video. One of the best I have seen on TH-cam for any subject. I just want to add that we have front/rear ARB lockers with 110K miles on them, and zero issues except for a melted plastic air line that was replaced with a stainless steel line. No leaks, no icing, etc. We can air up our 2 gallon ViAir tank (110PSI) and the ARB compressor won't trip (90PSI) for ~6 days. With front and rear locker *engaged*, and the Jeep parked, the compressor won't trip until ~3 days. Without the ViAir tank (we have a shut-off valve on the supply hose), the ARB's tiny manifold/tank will hold pressure for over a day before the compressor trips, and about 12 hours with the lockers engaged while parked. Note that we don't typically leave the tank aired up due to condensation and such.
Anyway, thanks again for the awesome video.
Thank you for the feedback!
great video mate! I only knew of Open, LSD and selectable before watch this, learnt a lot. Cheers.
Thank you for all the great and clear info !
I agree with so many others on here, this is the best explanation that I have ever seen. Thank you guys for putting this together! I hope that you continue to create more content like this.
So glad to hear it, we have much more in the works so make sure to subscribe!
The best locker/diff information video I have seen.
Thanks!
Thank you for this video.
I really learnt a lot.
Awesome
Great video 6 years later thanks.
At first I thought it was gonna be a long vid and im not gonna finish it, but when i kept watching I found out that this is The Best Differential break down on the internet! Thanks ben
That makes my day! So glad you enjoyed it!
Great info mate, cheers. Wish I had found this before I suffered through hours of contradictory videos. Subscribed.
Thank you!!
Best video and explanation of differentials that I've seen yet!
Well made video. Thanks for the thorough explanation.
this is by far the best explanation on the plant!! thanks .
Thank you so much!
Great VID. We have started showing this to our clients so they understand what they are getting when they buy a locker. Mike Walsman JeepFix West Jordan, UT
That's not the first time we've heard that from dealers and shops, so glad to hear we can help!
That was an amazing explication and thank you!
Excellent video with much needed information. Thank you
Ben, that was spot on and a perfect video!! Thank you for taking the time to explain each set up. Plan on an Ox Locker in the rear of my Jeep. But was stuck on what to do up front, until I watched your video!! Very informative indeed. When I'm ready to order, after this video, I'll purchase from you!
So glad to hear it, thank you! The OX locker is an excellent choice for a Jeep!
Actually I have trained my dog to engage and disengage my Ox locker on command. He is also a good navigator unless he loses concentration if he spots a pretty bitch on the trail. Seriously though, this is by far the best analysis video of the different forms of differentials that I have ever watched. Good job.
Haha! Thanks!
gotta watch this 3 or 4 times to take it all in great vid thanks so much
Thank you for showing us an excellent video !
I've seen several videos on this subject, this is by far the best of all, thank you very much for sharing, I took the liberty of sharing it on my group page... hope you don't mind.
Very happy to hear that, and thank you for sharing!
You are the greatest explainer ever! I want to ask you how everything works!
Oh stop, you're making me blush!
All the information required with nothing left out 👍 thanks mate. Great display too btw. Mega informative
...WOW!!!!! THANK YOU, BEN, VERY MUCH, FOR YOUR EXCELLENT EXPLANATION, AND DEMONSTRATION, OF THESE VITAL "DIFFERENTIAL" MECHANISMS!!
Great vid. I’m just confused now, didn’t know that exist so many diffs any lockers for my old 98 Hilux 🤨
Excellent description of the Eaton Truetrac. I agree, it is a brilliant mechanical design. It’s worth noting that they can make a “pop" or "boom" when unlocking...especially on dry pavement in a tight turn. I thought I broke something the first time I heard it.
MAAAAAAAAAAAAAN YOU'RE MY HERO!
I Have a truetrack in my 06 silverado. Made a uturn with wsy too much wood in the back and swore i broke my rear end when i heard that bang. Called the shop that did the install & they acted like i didnt know what i was talking about.
Nice to hear from someone else thats dealt with this issue.
@@michaelrichardson5505 Glad I could "help"! It scared the hell out of me the first time it happened. It doesn’t happen often with normal driving but I’m sure a u-turn would do it.
This guy does an excellent job explaining diffs in.a very clear and practical way
Great job.
Thank you that was the best presentation on lockers learned a lot. I’m leaning more with E lockers, thank you vary much.👍👍
I literally have probably only taken the time to leave one or two comments on a video in my entire 10+ year TH-cam career, and after being glued to this video from start to finish, I feel compelled to offer my sincerest gratitude for this thoroughly comprehensive overview. If only you had a tutorial for any/everything anyone ever wanted to learn about, would probably be the biggest lifehack of all time.
Thank you so much, I'm so glad to hear it and thank you for posting!!
Great video ! Thanks for the simple explanations.
If anybody is wondering why there aren't many vids on this subject, it is because of this video! ....very informative and very professionally done. Nothing beats a well presented, well constructed vid when broaching this sometimes confusing subject. Well done and many thanks.
One Ox manual locker, please.
One Ox manual in rear and true track in front please.
@@WilliamEllison I'm think this combo for my 98 XJ 🤔
@@WilliamEllison I'm installing this exact setup now. I'm hoping it's a great combination for on and off road performance.
Ox locker front and back!
Yes this video is long , but well worth the time spent.
So glad to hear that, thank you for watching!
Absolutely love this video very informative knew nothing about this subject and now I feel I have a grasp on it not good enough to teach it myself or nothing but I understand the concepts so thank you for the education good sir
Brilliantly detwiled video, thank you for sharing!
The OX can be locked by air, electric, mechanical, or the drive away lock. That's four options while being just as tough and costing less than an ARB.
Agreed!
Yeah but like no one in australia has a compatible car
My dad has a 2005 Silverado 2500 HD with G80 and it has 200k with no issues and still locks up fine.
Great video. Thanks for the thorough explanation of each item.
Best review on differentials! Thank you.
I think a Candy Machine Maker invented the True Trac idea.. Being the owner of Walter Trucks . The Detroit Locker Detroit True Tack I think they have been bought out is why the name has changed over the years.. I had one in the rear axle of a Tandem axle Truck .. It helped not to get stuck but was a real pain in the road.. You have to let off on the gas pedal to get it to unlock not so good when you are pulling a loader on a trailer up a steep drive and pulling into traffic and turning .. With a Detroit Locker only the wheel on the out side of the turn breaks loose and free wheels.. thus if you are under power it won't disengage which would cause the front wheels of my truck to slide sideways while turning ..
Excellent feedback, thank you!
@@Filthymotorsports Yes the only way a Detroit Locker will work is the out side wheel in a turn will ratchet or free wheel. With a big heavy truck Eaton 34,000 # tandem with 18 1?2 ring gears.. the only way I could get the truck to turn is to let off on the gas so it can unlock.. My Problem was I was pulling a trailer with 7,000 pounds of tongue weight which was way too much should have been about 3,000# 23,000 # loader 7,500# trailer
The Harrop/Eaton lockers (at least for the 80 series land cruiser) no longer disconnect between front and rear.
Thank for the info, do you have any more info on this or a link?
what makes you say that? They now use a ramp/pin design which works with same principle as ramp and ball bearing and still disengage and re-engage th-cam.com/video/1nYZo--7Xh4/w-d-xo.html
This man really knows his stuff!
And now I know! Thank you, great informative video.
Dang that ox locker is awesome. I just put in a Eaton e locker though.
Both are great in their own way, but the OX locker is very impressive.
Best video I've seen. Question for you about the torsen. My application is endurance road racing on tracks like Sonoma. I understand that when you are going around a corner with no throttle, the torsen allows the wheels to spin at different speeds. My question is, if I begin to throttle in the corner, will the torsen continue to allow the wheels to spin at different speed, or will it effectively become a locked dif. I have used a friction LSD and experienced significant single wheel spin exiting corners even after replacing the clutches. I have also used a Mini Spool (because I don't trust the bearings in a c-clip eliminator kit to last an endurance race with a full spool). I have much better grip and acceleration out of the corner with the mini spool, but experience significant understeer and increase in front tire wear as a result of the rear tires wanting to continue in a straight line. FYI, this car never sees public streets.
Thanks again for the great video.
Thanks for question, glad you liked the video! The TrueTrac is used a lot in road racing. On a high traction surface the power always goes to both tires while allowing them to turn at different speeds within a fixed ratio. I had a chance to race a Miata equipped with a Torsen earlier this year on a race track and it was very impressive and extremely predictable. The few times I pushed too hard and got sideways it was completely controlled and very easy to straighten back up. There was also no understeer or oversteer from it. Hope that helps!
Thanks for the response and feedback. I'll be talking to the boss about spending the $500 to put this in.
To clear up some common misconceptions about differentials (also found in this video, to some extend):
An open differential always splits the torque of the input shaft 50/50 between the output shafts.
A Torsen (TorSen = Torque Sensing) differential never locks up. It changes the TBR (torque bias ratio) from 1:1 (open differential) to something else. F.e. a torsen differential with a TBR of 3:1 will output 3 times the torque of the faster wheel on the slower spinning wheel. That's why torsen differentials aren't great in really bad conditions. If one wheel slips on a really slippery surface like ice or hangs in the air, the torque it takes to spin it is nearly 0. Meaning the other output will be driven with 3 x 0 = 0. Clutch pack based LSD overcome this problem with pretensioning, which provides a given torque differential that has to be overcome before it allows slip.
1. Open differential is 50/50 only on high traction surfaces.
2. While the TrueTrac does not mechanically lock, when enough torque applied to it and given enough resistance to "seize up", it will create enough friction that both axle shafts will turn together as if in a spool, although, in the real world this may only be for a fraction of a second.
@@Filthymotorsports1. "Open differential is 50/50 only on high traction surfaces." That is not true. An open differential always "applies" the same torque on both outputs, disregarding minor differences caused by friction in the differential. That is exactly why an open differential delivers poor performance on low traction surfaces, since the torque is dependent of the resistance of the wheels. When one wheel slips, the torque needed to drive it is close to 0, meaning the torque delivered to the other wheel also is close to 0 (and for that matter, the torque output by the engine being close to 0 in that situation as well.) That's also the reason why you need a rolling road/dyno to measure the power/torque output of an engine, and can't measure it just standing still and stomping the gas.
2. A Torsen style differential can of course spin both outputs at the same rate, if the faster spinning output is generating a lot of torque. What you discribe usually happens when the vehicle isn't moving and power is applied very rapidly. The inertia in the drivetrain will generate a lot of torque in the system for a very short moment, and therefore deliver a higher output (depending on the TBR of the differential) on the slower turning wheel. But as soon as the faster output is turning and slipping, the torque drops again. One way to counter that lack of torque biasing in very low friction situations with a Torsen differential is applying the brakes. The braking force will increase the torque needed to turn the faster spinning wheel, and therefore increase the torque delivered to the other wheel.
What posi unit do you recommend for street cruising? In other words "for the streets"
Iv watched many explanations this was far the best thankyou for educating me
So I could run a spool on my front diff on a tacoma, since I have Manual warn hubs, which means I can disengage my axles from front diff at the wheels when I don’t need 4x4. Would this be a good cheaper option for me????
Technically yes, however, you would have to be very, very careful with how you engage and use 4x4. We like lunchbox lockers for the front because they have a "fuse" function to them to reduce stresses.
HOLD IT!
At 4:09 - the small clutch pack.
"Very similar to what you would find in a MANUAL transmission..."
I'm certain you intended to say AUTOMATIC transmission.
OK.
Carry on.
:-)
Good job overall.
I remember the Eureka moment I had in 9th grade when I had a differential cutaway I could play with and finally see it for myself. It's very difficult to comprehend without one in your hands.
The reference was to the clutch used to shift a manual transmission but of course automatic transmissions have internal clutches as well. Cheers!
One of the best videos I’ve seen on TH-cam. Definitely five star. Thank you.
Thank you so much!
Great video. Most info i have ever found on diffs. Kudos
I want a torsen installed on my tacoma. . what kind of shop would you recommend?
My original response got lost when we changed over to a company channel but for those that have the same question, here it is again: With installation, you get what you pay for but one trick you can do is ask the shop to send you a photo of the final gear tooth pattern and backlash measurement or, better yet, ask if you can stop by so you can see it for yourself before they bolt the differential cover back on. Any shop that says no to this request should be avoided. Hope that helps!
How do vacuum actuated lockers like the ones in the Nissan Patrol work?
I am not familiar with those, where could I get my hands on one to find out!?
The Patrol rear locker is a vacuum actuating locker. It has dual vacuum solenoids in the engine bay which provide vacuum to either of the two hoses running to the rear differential. Vacuum is supplied to one hose constantly to maintain the correct position of the actuating rod to normal open differential use. When you flick the switch vacuum is switched to the second line which slides the locking rod across into the locked position. When you switch it off vacuum is returned to the "open" line and the differential will revert to open again.
@@AfkhamAzeez sounds like exactly the same principle as a Pnuematic actuated differential locker. The difference is they are using the vacuum generated by the engine instead of a compressor to move a pin that locks the spider gears.
One of the best video that describe me about diff locks......!!
I’ve got Eaton E-lockers front and rear, and I wish I watched this video first before getting them because I would have went with Ox lockers front and rear instead.
How are the Eatons treating you? And which OX mechanism were you referring to when when you said this comment? The manual ones?
@@RegardlessRecords the Eaton e lockers are working just fine. Haven’t had a single issue with them at all. My buddy has them as well and somehow he burned up the diode for his rear locker. It was literally on fire in it’s little case. He just swapped it out with a new one and it’s been fine. But they’ve worked every single time I’ve used them. Can’t complain really.
@@RegardlessRecords and yes I was referring to the manual ones. Seems a lot more reliable to be able to just move a level and your locked, as well as the ability to use that tool in case the cable breaks so you have a backup to unblock. But like I said I haven’t had any issues with my Eaton e lockers. I made that comment before I actually had the ability to use them. Now that I have I don’t know if I’d switch, just because there haven’t been any issues with them.
@@StormbornJKU thank for the reply. I figured you were talking about the manual ones. Watching this video it does seem like something crazy might happen with the air or the electric ones. Then I was thinking to myself well a car has a lot of electronic components that last a life time so i figured I'd ask how you are liking them so I can figure out what set up im leaning towards. Thanks for the reply.
Wish someone made a 35 spline (detroit) locker for a 12 bolt. I have a spool now for drag racing and it works but it's pretty hard on parts given the two 180 degree turns at my drag strip.
This was very informative, thank you
Amazingly informative video that covers a really needed explanation on a topic that not so many covered so well!
Thank you!
Exceptionally comprehensive explanation of lockers minus one issue... torsen style diffs, like the truetrac, freak out when both tires are on ice. I found that out on my Jeep XJ when the rear end swung from side to side when I hit some black ice at 60 mph here in Colorado. This wasn't just a little swing, but more of a full blown watusi that even the best of your favorite club dancers couldn't replicate. ARB air lockers for me from then on out. Only thing that saved my life was mashing the transfer case into part time 4wd "RIGHT NOW" at speed and it straightened up. Great diff for everything else, just tap the brake if a wheel gets off the ground on rocks, great on sand, mud, gravel or even if a wheel gets in a soft shoulder and one on pavement.Awesome in snow too. Ice? Holy crap, hold on to your wheel and say a prayer because you may be going forward looking through your rear view mirror.
Thanks for the feedback!
My experience with the TruTrac going from snow to ice on a dirt road at 45 mph in a long bed, 4 door 2 WD 84 Chevy, was different from the former comment. I'm not discounting his experience, but mine was a positive outcome. Power went from wheel to wheel and kept me in control. My friend and co-worker in front of me in his 92 Dodge short bed 4x4 in two wheel drive almost lost it. I'm not sure if it was the wheel base difference or what, but in my truck the Tru Trac works for me.
Robert Rudd where can I purchase a torson Eaton trutrac diff? Everywhere I look has Eaton Detroit locker diff but don’t say torson.
@@brandonminson2460 It's called Eaton Detroit Truetrac. drivetrainshop.com or pretty much anywhere amazon ebay ect.
Proper studded winter tires, problem solved.
