What gear ratio do I need for a lifted truck? That is the question we are answering in todays video! We explain what Gear Ratio's are, and which one is best for you! 3.73 gears are the most agressive gears you can get from the Ford Factory. Then you have 3.55 locking differential for that person who needs acceleraton and towing capability without messing up the Fuel Economy.

A 3.55 gear ratio means the driveshaft turns 3.55 times for every revolution of the axle, not 3.55 time of the engine.
Beat me to it.
i caught that too
My truck has a 3.55 gets a whopping 12.3mpg 🤣👍
Why cannot you give names to gear ratios? Racers that have earned it. I just want the Ken Block Gear Ratio, lol
Thanks for pointing that out, it inspires thought and makes a lot of sense!
Great to see your passion for ford trucks. I love my f150. So love to see any f150 content.
Like all you guys videos! I have a late model 2015, 3inch lift, 5.0, 6speed and 34x12 nittos on 20x10 wheels. Gears are 3.31 and I tow a boat quite often. Seems to do way better than my old 04 ,f150 with the 5.4 and 3.55 gears.
Most of us raised on cars and trucks know this but were are never to old to learn. Keep the info coming.
smart man
I honestly never knew what the difference was in ratios. Now I do! Lol this was helpful in knowing what's up. Thanks man!
Great practical explanation of selecting a rear axle ratio.
Had an 01’ F150 with a 5.4 and 4.56:1 we did 15k hit 37 states pulling a 25’ 7700 pound airstream and got about ten miles / gal. but only got about the same the rest of the time, 2000 rpm @ 55 mph. In overdrive , the only time I was on the freeway was with the trailer . Worked very well and fun to drive .
Thank You for a great explanation. T&C channel adds great content in a perfect length of time. Your delivery of information on ford products matches that perfect blend of clear narrative with friendly, no nonsense facts.
Glad it was helpful! Thanks for the kind words..
I'd like you do a really good show and tell on the Mach-E when you get one in. I pre-ordered one for my wife and have been reading all the reviews. I'm super excited about it. I like the detail you put in your videos. If I lived closer, I would totally buy a vehicle from you.
I have a 2017 5.0 XLT with a 3.73 final drive & regularly get almost 20 mpg! I drive it like it's my baby, because it is. You won't see any brake dust on my wheels as I save my brakes along with fuel, even though the 3.73 is there whenever I might need it!
awesome, Still love the 3.55 rare ratio, sweet spots, I am from Canada, still love the content
Great information i have a 2018 F150 STX Sport with towing package good truck water pump went out 11 months after i bought it but so far so good
I got 3.92s on my 2016 Ram Sport. Absolutely love them
I went from a 2012 3.5 Eco with the 3.73 rear end to a 2019 3.5 Eco with a 3.55 rear end and 10 speed. I have to say that I miss the 3.73 rear end but on the plus side I averaged 16.9 MPG towing my 2500lb boat/motor/trailer on a 2000 mile fishing trip. Not bad for a gas truck.
In 2018 I ordered an F-150 Platinum 4x2, 5.0, 10-speed automatic, 3.55 Locking Rear End. I was going for a max payload Platinum (1,750 lbs) for towing a 6,300 lb Airstream. Best truck I ever owned, and it has more than enough power to pull the trailer up the steepest grades and get back down safely too. My highway mileage towing averages 13 mpg.
Randall Godfrey just wondering sir why did you buy an expensive model in 2wd
@@TheBigFunOne 2wd vehicles have higher tow ratings and are more economical for towing. The over the road trucks are 2wd vehicles. I also live in Florida where there isn't much need for 4wd. I did get the locking rear axle, which I had on my previous 2wd truck, and that always worked when I encountered a slippery road and helped me pull the trailer out. 14 years without getting stuck so far. There are features that only come with the premium models that we wanted, and the wife says if she is going to ride in a truck, it has to be a nice one. Thanks for asking.
Randall Godfrey interesting. How much do you want to tow? Because a 4x4 ecoboost can tow 10k lbs easy. You never know when you might drive to minesota in the winter with that truck. 😂
MrInzombia not likely. A 4x2 EcoBoost can tow more and has a higher payload than a 4x4. I think the V8 has a higher payload rating than the EcoBoost. I was going for max payload. Also, the reliability of the V8 is higher than the EcoBoost.
@@MrInzombia haha @ 10 "easy" lolololol "EASY"
Great video. Everything you explained makes sence. Thanks
From Saskatchewan, Canada.
*sense
Great video and I can understand you pretty good with your Alabama accent even if I am not a native english speaker.
Out here in Germany we just have mid-size trucks (all Diesels because of gas price and mpg) and they haven't been very popular until a few years ago (maybe because of the VW Amarok). But we always had some grey imports of fullsize trucks. But it seems like more than 80% of them are RAM's. But I like the F150 better also because of your videos. Great content your videos. Wish I could have done that when I was a car salesman (VW) years ago.
Greetings from Bremen (Beck's beer City)
You did an awesome job! Immediately after watching the video, my wife who was sitting right next to me said "I know nothing about trucks, but he made it so simple to understand" . 😂
Thank you for this video! So many people have no idea how important gear ratios are and hopefully this will shed light on the topic to many people.
I been looking on trucks, right now i have a small kia forte. and where i live when it rains man the flooding is bad. several coworkers had lost there cars. so that is the resosn in looking for a truck, and I see those options of gear ration without understanding @#$@#$. so yes. Perfect explanation, now i do understand this, thank you so much.
This was perfect I want to get a single cab and I wanted for racing,know I know what will work for me . Good video!!
Thank you for getting me learnt! These videos have been very helpful guiding me in my purchase of an f150.
Hi Mitchell
Great great videos man.
I've learned so much. Thank you for the awesome knowledge. I have a 2019 150 stock 2wd 5.0.
Ford has just knocked it out of the park with their trucks the past 5 years. Power and economy. Love it man. Keep up the great work. Us blue oval guys love it.
Also....
Do you have future plans to do a video on engine comparisons?
Definitely helpful for the people who don’t know anything about it! Thanks!
Really great video. I don't know how many times I have come back to watch it. I get the physics behind gears and ratios, but applying the concept to a real-world application (like my truck differential) ... uh... _system not responding_. At first, I was That Guy your were talking about at the end of your vid, "...confused the crap outta ya..."
BUT as I started to explore more, really "think" it though, and watch this video a hundred times - YEAH! I really appreciate your straight talk and examples of when/why you would want a different set up. Especially talking about your own truck!
I have a 2018 F-150 V-8, 10-speed. Going to lift it soon. I am also thinking about eventually installing manual lockers - doing that research is when the lightbulb started coming on. I was bothered by all of the information floating around about the bigger/heavier wheels bogging down the truck, wrecking performance, the 3.31's would make it suck, blah, blah, blah. This video was VERY HELPFUL!
I think I could apply your information to the off-road performance aspect, but I would love to see a similar video that talks about gear ratios on lifted trucks with 35's in off-road settings (not from a heavy towing or acceleration/racing perspective). What would be the best ratios for a work truck/overland truck that might also be a daily driver or frequent freeway commuter? (A pink, flying unicorn, I know...)
Love the channel!
Thanks for this. Higher number- higher tow, lower number- better mpg
I appreciate this, when my friends talked about the rear ends in their trucks all I knew was my F150 had a 3:55, had no ideal what that really meant, had a 72 302 3 speed in the floor Mustang with a 3:08 rear end and it was dog slow, but it was Carolina blue with Creggars and such a pretty car.
I have 2 F 150's super crew cab XLT's, both with the 5.0. One is 2011 and the other is a 2016 both with 3.73 gears Love that gear ratio
I love the performance of my 18' 5.0 f150(10 speed) with 3.55's with stock tire size (32"). If I were to put 33'' tires on I would need to regear to 3.73 to retain stock performance. If I put on 35"s on I would need to regear to 4.10 to retain the performance of my stock f150 with 3.55's. 37'' would need 4.56 gears. Of course, you can regear the axle gears for bigger wheels/tires all-day but will never regain fuel milage of stock, and you can certainly run 3.55 with 35''s just fine. But I have blown up a transmission in my older f150 doing just that towing a trailer cross country
Definitely some things to consider when choosing the gear ratio, and this will certainly come down to the individual driving habits and needs of the operator. I chose the 3.73 ratio for my 2020 F150 5.0 as I knew going in I was going to be running taller tires. Running taller tires is going to impact your 'effective gear ratio', but that's a whole 'nother subject. Do I get fantastic gas mileage? Not particularly. Do I care? Nope. What I do know is I rather enjoy the acceleration off the line factor. Added the locking differential to the package too as that could very well come in handy while driving on the beach. I think the 3.55 gears are a good compromise between gas mileage and acceleration for people that aren't towing/hauling heavy loads or running taller tires. If you're using your F150 as a towing/hauling workhorse, or running taller tires, I'd have to say 3.73 is the better suited ratio.
Which gear ratio would be best for a single cab 10 speed 5.0 f150??
Looking to use it for just street use quick acceleration and speed
@@grandmastagrimm8773 3.73 is the best gear ratio out of the factory for acceleration.
@@grandmastagrimm87733.73, that's what I ordered with mine, 24 rcsb coyote, I wanted max off the line acceleration, don't care about mileage so much lol😅
Great explanation. Just made my decision on which truck.
Thanks for the video, man! I've been building and pricing a new vehicle on the Ford website and I've had no idea what gear ratio to pick, and didn't bother to ask. Now I know exactly how to pick one. 👍🏼
Don’t worry about the accent! I’m born and raised in Florida. I was stationed in both South and North Carolina. I kind of know the difference. Great videos with stellar information. Plus, I’m a Ford guy anyway. Looking for my retirement truck!
Love my 2019 F150. I get 21mpg average highway and city with Ecoboost 6 and 3.55 gears.
Love the informational videos! Thanks so much...
Now, do an acceleration comparison video between the two trucks. That’d be good to see.
DO IT!!
Very helpful explanation. Thank you!
Great video. You made it easy to understand. It’s not easy making informational videos.
Excellent and simple explanation! Thanks man.
I think you did great on explaining!
Fantastic Video as always!! Well explained!!
Jonathan Monts if you enjoy misinformation, sure!
I own an 09 F250 with 3.55’s. I also owned two 78”s with 4.10”s and the 4 speed manual with granny gear. Those were screaming in 4th at 60-65 mph.
Ive got an 87 with a C6 three-speed with super aggressive gears, 3k at around 65. I just ordered a 2020 5.0 with 3.73. The 10 speed 3rd overdrive puts it at 1750 @ 70mph, Pretty amazing.
basically, this is like gear on a bicycle, thanks for info!
Another very important variable to add into this equation would be tire diameter. If you go on 37" you wanna have a 3.71 or higher to compensate.
What about 35’s? 3.71? Or 355
Truly very informative. Appreciate you bro
2018 XLT extended cab 4x4 5.0 10 speed trans, 3.31 gears, 285/75-18 Toyo AT's (35"). 16-17 MPG empty, with 3 other almost adult family members it starts gear searching, hooked to a 6x10 utility trailer or 14' aluminum boat, motor and trailer....12 MPG and constantly gear searching. I can be traveling into a head wind empty and truck starts gear searching. Love the truck and engine, just wish it had a 6 speed transmission or Wish I had 3.73 gears or both.
I wish you would’ve touched more on the 3:31 since that’s what I have. I haven’t towed with it yet but love how I can get up to 21 mpg and the rpms are under 2,000 on the highway.
I have 3.31s in the 5.0 and the towing capacity is 8400 lbs max according to the manual... I have a lot of aftermarket upgrades on it (intake, headers, exhaust, wheels and tires (32ishs) Detroit locker, 4 inch spindles, upper control arms, Bilstein 5100s, super chips programmer) and it tows light stuff like it isn't even there. That said when towing the big trailer (16x8x7) home we just got it did fine empty however I'm regearing it to 3.73 because that puts my towing capacity up to 10k because that trailer is big and heavy and when it's full I don't want to take the chance with the 3.31s
331 is your basic.. made for top end... if you tow you will notice more down shifts and higher revs even with a 3.5 EcoBoost.
What speeds are you doing for that rpm at 60mph? I'm in Australia and just doing my research as I want to buy one.

Mitch, that video was extremely helpful. I'm currently buying an f150, and hopefully, I'll get that higher gear with the Roush.
"I like to drive it like I stole it." Absolutely love that line.
Helpful and informative. Thanks
Helpful, thanks. I want to take vacation and buy my truck from you guys.
Thats a decent explanation. Most people don’t even consider gears when buying.
Great job. Not confusing at all.
Nice job, clear explanation
Very helpful. I'm looking at a off road roush f150 and I forgot to even look at the gear. Now I'm going to want 3.73 gears in it since I have a heavy foot lol
A lot of the newer Roush F-150’s are now coming with 3.73’s. The earlier Roush F-150’s had 3.55’s
Very good job of explaining!!
Thank you, I got the message that you were giving.
Very helpful video! Thanks
I ordered a 16 with a 5.0 and 3.73. I also have an 11 with a 5.0 and 3.55s. Absolutely love the 3.73. The power difference is dramatically more with the 3.73. I have considered having 3.73s put in the 11 but don’t want to spend 2000 dollars. I highly recommend 3.73s. I only get 1 mpg less on the hwy but I get 1 - 2 mpg more in city driving with the 3.73s. Do yourself a favor and get 3.73s especially if you tow anything!!!
Great Comment! Ford F150 - the 5.0L V8 and 3.73 gears is the only way to go!
Check out PaxPower -----> PaxPower.com and read how they can turn a regular Ford F150 4WD 5.0L V8 into a better truck than a Ford F-150 Raptor off the assembly line.
PaxPower will install a factory Raptor suspension ($7000 installed).....OR.....a better high quality Icon suspension (about $8000 - $8500 installed).....and a Whipple Supercharger as an option. The custom build Ford F-150 4WD will Ford F-150 Raptor's lunch all day long...both on paved roads and off-road.
Always enjoy your videos.
Thank you very helpful video and very informational
Thank you, this was helpful
Thank you for explaining this
My 2023 Lariat has the 5.0L with towing pkg and 3.73s. I have no intention of towing anything at all. I don't care much about mileage. But I smile every time I step on the gas pedal.
The video was very informative.
Awesome video! Thank you!!
Wow you read my mind . Thank you 🙏🏻
Last week I bought a brand new 2020 xlt sport with the 2.7 eco and 3:73 gears. She likes to scoot!! Plus I’ll be towing my 5800lb trailer with it sometimes which helps. Love this truck so far.
What kind of fuel mileage have you been getting with the 3.73 gear ratio ? I am of the opinion that a person wouldn't really know the difference. Truck shopping and the 3.55 seem to be the most common.
@@jetboy770371 I’m getting around 22.5 mpg with it. Also with the different gear it upped my tow rating a little also which was nice.
You really only talked about the importance of swapping the gears as it relates to towing. But another and probably more important piece of it is that when you go up in tire size, and don’t change the gears, it wears out your transmission, axle bearings and pinion. I put 37’s on my 1997 F150 4x4 and it wore the transmission out in about 10,000 miles. The transmission guy told me the whole transmission was shot, they had to do a complete rebuild on the transmission, right after the transmission all the axle bearings an the pinion went out. I ended up putting 4.88’s on it and it’s like a different truck, it hauls a$$ even with the big tires and gets almost twice the mpg than the stock gears. 33’s and maybe 35’s are probably ok to run with stock gear ratio, but any bigger and you have to change the gears.
RACING! That's what I'm gonna be doing with my truck! Oh, and going to work...ugh...yeah...that, too.
WOULD BE A PERFECT ADDITION TO MY 2018 F150.
Thanks you did a great job 👍
Oh wow!!
Nice looking!!
Very good video, thanks!
Yes sir thank you for your video. I now understand gear ratio
My brother had a F-150 with the 3.31 and when he put 34 inch Nitto Ridge Grapplers on it and it killed his mpg by 4 in the city and 3 on the highway. I had the same tires on my Toyota Tundra with a 4.30 rear end and saw no reduction in my mpg. He ended up trading it in for a 3.73 last year and only lost 2 mpg city and 1.5-2 highway. He was much happier.
I have a Ram 1500 with the 3.92 axle ratio and absolutely love the feel off the line and whenever I want to pass people. I don’t tow at all or carry anything heavy often but that off the line feel is awesome. Yeah mileage is pretty bad compared to my buddy’s with a different axle ratio but it’s a truck so I don’t care plus it will be better for me once I lift it to help with drivability.
What are the differences in Highway speed? I got 3.55 in my 04 1500 so 95 is easy to get to, when you went to 3.92 what’s your top speed comfortably?
@@cliftonsargent1572 honestly it was comfortable at the speed governed limit of 105-107 as long as it wasn’t to windy out at that point it was just aerodynamics coming into play making it feel floaty. Power was never an issue and it was still pulling up until it hit the limiter that I didn’t have removed because my tires weren’t rated for a higher speed than what I could go.
@@THEDESTROYER711 ok so you were able to cruise at 65-70 and not be at or over 3k RPM?? That’s the only reason I haven’t purchased a back Axel with the 3.92 gears in it
@@cliftonsargent1572 with the 8 speed transmission at 80-85mph I believe it’s about 2000-2200. The last couple gears in that transmission are cruising gears so it drops the rpms pretty low for that speed.
@@cliftonsargent1572 if you have the older 4 or 5 speed tho I don’t know how it would really effect that tho. I wouldn’t imagine anything more than 500 rpm higher. I’m sure there is some sort of calculator for that.
Great video. Any chance we can see a drag race between these trucks/gear combos? Maybe in all XLT trims
Thanks for the education and detailed breakdown of the gear ratio, very helpful. What difference do the tires make (size of the tires)?
Work=ForceXDistance
So when you lose one distance (the engine spins more) you gain in force (more power to the ground)
Nice video.
You don’t get more power to the ground, you get more torque to the ground via mechanical advantage
Very helpful thank you.
Great videos , very helpful !
First off I like these videos, very helpful. I would like to hear more about the effects of the different gear ratios. For example 0-60, RPM @ 60 & 80, MPG @ 60 & 80 and maximum towing weight. Again great video.
It's a no brainer. Higher gear ratio means more revolutions of the driveshaft, which causes more friction, but also means more acceleration, more torque, and that friction causes worse gas mileage as you go higher. If the gear ratio is too low, it can make it difficult to move heavier tow/payloads.
This video was very helpful
this was a great vid! but now I need help to figure out if I need electronic locking or non-limited slip.
Awesome and great explanation, great video and thanks a bunch. Great appreciated!
You are the best on information and I love your videos! I buy a lot of trucks from makhiak in Texas. I want to know about the 331 rear end in the f 250 before I buy
I liked the video, but researching this topic I have to say there is a lot of conflicting opinions regarding how much stress it puts on the drive train when using bigger tires etc
so helpful and love the accent!
Thank You, good job and well done
Good video and info. My 2015 eco boost fx4 has 3.55 gears which pulls my 6x12 utility work trailer like nothing even when fully loaded.
Already with just 3.55 gears, my tired will peal with very little gas. The rear ends are light
Which engine sir?
@@Gypsum-pro 3.5
extremely helpful!
Awesome vid. Drive it like you stole it ! Very good break down. More people need to know what the final druve gearing does. Btw I'm ln market for a 6.7 super cab short bed dually.2021. Doesn't seem to be common...can ya'll help?
I have a 2018 STX 2.7 eco, I have the 3.55 gear ratio and it has a 7” lift with 325/60r20. I can tell you 3.55 makes it feel sluggish. Maybe if you have a 3.5L ecoboost it may be a different story. I’m swapping my gears next week to either 4.10 , 4.30, or 4.56. I did get a Tune which helped a bit but I feel swapping gears to match the bigger tire size will be much of an improvement. We will see once I get them installed with the verdict.
Did you do this? What did you end up going with and are you happy.
Good vid mitchel!!
If you live in the Rocky Mountains you go as low as possible or regret it, the high altitude and steep hills make everything feel under powered
Tom Fairbourn that’s where the eco boosts shine! Watch tfl towing Ike gauntlet videos eco boosts were the only engines that still had throttle left! Amazing engines
Andrew Medeiros the turbos help but they still suffer my own experience
@MANSQUITO 3.55 I wish it had the 3.73, one day I may change them to 4.10
Thanks for your video. Soon I will be shopping for a new F150. I will be pulling a 7000 lbs trailer most of the time. I think the 3.55 combined with either the v8 or v6 turbo should be OK, thanks for a 10 speeds transmission. Still didn't make my mind about the engine.
The 3.5 Ecoboost with the 3.55 Tows like a Beast.
Very Helpful. Thank you
This was very good thank you.
very helpful.Thanks
