- Installing new gears with a higher ratio or what some people call, "re-gearing" is something that you'll want to have done after bumping up to a bigger set of tires on your Jeep Wrangler or Gladiator. In this video, you'll get learn what you'll want to run and why, see what all is involved in having them installed, what you'll need to do to get your Jeep's computer to recognize the upgrade and how to properly break them in. A BIG THANKS goes to Jeremy and Chad over at Disciple Offroad for helping us to make what you're about to see possible.

I re-geared my 2020 Willy's that has 35's on it to 4.88. It made all the difference in the world on that jeep. I thought it may have been too much gear but I thought I could increase it to 37's but no need. Accelerates so much better, driveability in town and on the highway. I did it myself and actually really enjoyed doing it. But it was a lot of work and I get why it's so expensive. I used the revolution gears and they set up very nice. Great cuts and centered well with a good pattern. Good video and I think with oversize tires that so many jeeps have installed the gears are the best modification you really have to make! I used BFH garage channel to get through any gotchyas for the metric axles.
What transmission do you have
You really make the best videos. Very informative. Another great video.
Glad you like them!
Appreciate you two coming all the way out to see us and trusting us with your gears! Always a great time with you guys and glad you are enjoying that 8th gear again 😎
Are you kidding?! Having had previous experiences dealing with shops who really screwed things up, you guys are one of the very few across America that I would trust to work on our Jeeps! That is no lie! Of course, we always have a great time with you and Chad and always appreciate your attention to detail. 8th gear at a nice low RPM at highway speeds has been awesome to have again 👍
Did you have a shop in Florida 😢 or do I need to drive there. Crazy lot of work but clearly show how hard the work is and how easy someone can f things up
Thanks for making the video.
What is the cost for 4.88 gears on a 3.6 Sport S max tow? I currently have 35s but plan to move to 37s.
I live in Las Vegas and can make the trip to Cali.
@@mrjeffry25 Sorry, I am not familiar with any shops in Florida but I would imagine there are a lot that can help you out.
I like how you showed their struggles lol! Some stuff puts up a fight!!
LOL - just trying to keep it real 😎
@@Daniel357blue42 nothing goes perfectly smooth 😎
Please open a shop here in Jacksonville, FL...... 🙂 🙂 It's so hard to trust someone to do this correctly!
I’m about to regear my JL sport unlimited to 4.56s! I’m excited. Perfect timing for this video to come out
I’m running 315 70 17
3.6L 8 speed automatic
That would be a good ratio for your tires.
Perfect timing, getting ready to have my JLUR re-geared for my 37’s, going with 4.88’s as well. Thanks for another awesome video guys!
Glad you could appreciate the video and I think you'll be happy with 4.88
Great job on the gears, Jeremy and great video, Eddie and Cindy! I learned a lot about gears and how I’ll never attempt doing them on my own! 😅
Happy to hear you liked what you saw and yeah, I'd prefer to trust people who do this on a regular basis.
Great video and I enjoyed the input on gear ratios versus tire size. A lot of people just want a simple chart on what gears with a certain size tire, but there are so many variables to consider when picking gear ratios in addition to tire size. Things like tire weight, weight of vehicle, towing, engine, transmission, vehicle use, etc. should be factored when picking a ratio. My JT 3.6 auto is a daily driver with frequent highway miles and no towing. I chose 4.56 gears and they work great with my 35 inch load C AT tires! Thanks again for the very informative video!
Awesome, I think you chose wisely and glad you enjoyed the video.
Awesome detailed video of what all is involved. Very helpful for anyone who does not know.
When you Watch the Video… Why would anyone Complain what a Shop would Charge to do a Good Job installing a Set of Gears… # Getitdonerightthefirsttime👍
I totally agree and I can tell you, Disciple is one of the more affordable shops out there.
@@fwschnaar3179 thank you. And yes most people don’t like the prices for gear work but also don’t realize the work, specialty tools and experience to do them.
And now we know 😊 🇺🇸 👍
LOL - glad we could share this with you 😎
Hanford?! I used to live there. I never knew you were close to there. Great vid as always
Actually, we're not that close. We live in Carson City, NV but are always happy to make the drive out to see our friends 😎
@@wayalife oh that’s makes sense.
Dude….. you totally left us diesel guys out of the discussion… diesel 37/38’s 4.56 40’s 4.88’s?
LOL - not really. Jeremy does mention that something like a diesel will make a difference with what you can get by with but ultimately, every vehicle performs best with the ratio made for the tire size you're running and how you intend to use your Jeep. This would include vehicles with a V8 and believe me, I own 2 of them.
@@wayalife It’s cool. It is up for debate pretty much everywhere with the diesel. :| emissions is a big factor too. 4.88’s and 38’s happy here for the most part. Made a HUGE difference to dropping oil temps when going through the mountains (did not completely resolve- but significantly helped….) 🍺😂 great video! Thanks!
@@Escape.Idiocracy we actually just installed 4.56 gears on a Diesel with 40’s and can tell you that even that ratio works surprisingly well but for my style, I would have leaned more towards 4.88’s. Again, there are some gray areas that are personal preference 👍🏼
I regeared my 2021 Jeep Gladiator Max Tow to 4.88 with 37 inch tires. It’s a much improved truck now. The 4.10 gears struggled. I hardly ever saw 8th gear. I would be in 5th gear on the highway if there was strong head wind and a slight incline. The 4.88 gears brought my Jeep back to stock. Smooth shifting and a much more enjoyable experience.
Glad to hear you are seeing the same thing as me 👍
Thank you for the insight. I have a 2018 Wangler Rubicon with a 3.6. I have 35's on my Jeep. I will be towing occasionally, so I think 488 will be good for me. Thanks!
Being that you are wanting to tow with your Jeep, I think 4.88 would be the right choice.
Long way from Nv. Eddie! Haha. Have never been to Disciple Off Road, but they used to be close when I was in Fresno... now in Idaho and that's just a bit too far! Lol. Thanks for the video. 👍
Glad you enjoyed the video 😎
love see guys with passion do their work these are the guys you want working on your rig!!
I totally agree 👍
thx alote for all this precious info :P have a great day all
Glad to hear you found our video to be helpful 😎
Awesome info. Looks like great shop!
Glad you enjoyed the video and yes, if you live in the area or are willing to make the drive, Disciple is who I would recommend.
@@xmonger thank you sir 🙏🏼
What cover did yoy use for the differential? Look super nice
The cover is made by Currie, just like the gears.
Thanks, great video! Very informative.............
Glad you enjoyed it!
Definitely not a job I would want to tackle.
14:38 I like the way he uses the box to track diff parts.
LOL - glad you enjoyed it 😁
Another great and informative how-to video.
Happy to hear you found it to be informative 😎
Great as always! $6.99 for gas!!! 😮😮😮
Tell me about it!! California!! 🙄
40,s and 5:13 Revolution gears work Great on My 23 Willys Gladiator 🇺🇸💪✌️
👍👍😃🍺🍺
What about 33s on a Sport wrangler?
Honestly, I personally wouldn't waste the money regearing for just 33's. I've run them with 3.45 gears and thought it was fine. With 3.73 or 4.10s, it's all you really need.
13.9 MPG. Did that go up or down? 😊
LOL - good eye and considering most of our drive was going up and over the Sierra Nevada Mountains the long way, it was up 😎
Awesome Outstanding job thanks
Thank you :)
So good to see a new video guys!
Happy to hear you enjoy our videos 😎
I'm running a 2020 JLUR with a 3.6L Auto, and just a few months ago I transitioned from 35" Falken Wildpeak A/T tires to 37" Falken Wildpeak R/T tires. About a month later I had my Jeep regeared with Revolution 4.88's, and after doing the 500 mile break-in I had the differential fluid replaced. All was good for about the next month, but then the Locker idiot light illuminated on my dash. Since then, my Locker idiot light is constantly illuminated and my lockers will not engage. No offroading or locker engagement was done during that initial month after the regear, but once that Locker idiot illuminated I did try to engage my lockers and they would not engage. Be aware that after the regear and before the Locker idiot light illuminated, I was simply daily driving my Jeep on city and highway roads (aka. no offloading). Has anyone else run into my "lockers won't engage" problem after their regear? ...Next week I have an app't with the 4x4 Shop that did my regear. Any ideas on what they might find to be causing my lockers to not be able to be engaged?
Could be something as dumb as a wiring problem. Maybe the plug wasn't plugged in all the way on the inside. I would definitely have the shop take care of it as it would be an issue that they created.
Nice video. Interested in when you think axle shafts are necessary. I was thinking about RCV's and chromoly axles. Hate to do it, but the time to do it is with gears...
What do manufacturers do that you can drive it off the lot without any worries? I think all I saw in a Ford manual was no towing for 600 miles.
Me personally, the time to do it is when you actually need it. I've always found factory shafts to hold up well. Also, having run RCV on several Jeeps, I can tell you that you'd be better off running standard chromoly shafts with full circle clips. They're $400 more affordable and won't pop and snap loudly on the trail after hard use the way RCV will. Oh, and RCV will tell you that the noise is totally normal and they will not warranty it.
On 37 inch tires on 3.6 engine 5.13 is the best option dana 44. 2020 jlur. Tried both 5.13 is better
Clearly, to each their own. As I state in the video, I've run 5.13 on our first JL with a 3.6L and it was fun to have the extra power. That said and based on experience running 4.88 with a 3.6L, I knew it's what I'd prefer on our new Gladiator. Performance is same as stock and I really like running at a much lower RPM at highway speeds. Still feel like I have plenty of performance and have better fuel economy too boot. To me, 4.88 with 37's is better. 5.13 is perfect with 38s
Love my 5.13 on my Gladiator Rubicon with 37" tires. Glad I didn't go 4.88
Clearly, to each their own. Having run both, I can say that 5.13 is nice but for daily driving and fuel economy, 4.88 has proven to be a better fit with 37's. Or at least, from what I have seen.
As alway great informational vid. How much lift (inches) do you have on the rig. I like the stance with the 37’s
Happy to hear you enjoyed the video and what you're seeing is our Gladiator sitting on an EVO 4.5" lift. I specify brand only because no two lifts seem to measure the same or at least, from what I have seen.
Would you do the same sort of gearing on a manual transmission? I have a 2018 Wrangler Rubi with a 2 inch lift and 35's. I feel like 6th is useless and I loss some power after 4th into 5th.
Hard to say. Assuming your Rubicon came with 4.10 gears, the cost to upgrade to 4.56 is pretty high for just a bit more performance. However, if you're okay with losing fuel economy, bumping up to 4.88 will give you a lot more power.
I never really get the reason about break in what happens if you buy a brand new truck you don’t break them in
From the factory, mass produced axles have gears that are manufactured and specially treated to prevent the need for a break in. This process is to costly for a shop to do on just one set of gears.
Didn’t close and open the door 2x like the programmer instructed.
LOL
I wonder if you only had 35's with a 4/10 would you notice a big difference ?
Not between 4.10 and 4.56. For me, I wouldn't make the upgrade.
Why does nobody talk about the fact that there are portals? This is an opinion also given you a tun of ground clearance while yes there are pros and cons to both there is a other
LOL - Maybe because they cost $25K just for doodads that bolt onto your existing axles and only provide ground clearance down the middle of your Jeep. And really, ground clearance down the middle of your rig isn't everything, especially if you learn how to wheel your Jeep and learn to put your tires ON top of obstacles. For me, a guy who can afford portals, I assure you they would be on my rigs if I really thought they were so awesome. For the money, I'd rather have 1-tons and money left over to make real improvements to my Jeeps. But of course, that's just me.
… and this are the 37 inch tires you can’t have in Australia 😅
Awe, what a bummer.
Maybe I missed it, did you change the front gears as well?
You missed it. See video from here th-cam.com/video/bNlCEE3Xwj4/w-d-xo.html
A gladiator with a diesel and 37s what is recommended?
Honestly, I personally would still recommend 4.88 but you can get by with 4.10 if that's what your Jeep came with. Somewhere in between would definitely be 4.56
Getting ready for new gears 22 392 jeep on 37s. After watching this, I am going with 5.13s. I really think it will compliment my hemi off the line. Run the exhuast open and someone is always trying to gap me.
I personally would give that another thought. A good friend of mine is a senior engineer at Jeep and he assures me that the 392 was made to run 38's with 4.56. I have personally tested this out and can confirm, that setup feels very much like stock. At most, I would go 4.88 for a bit more power. 5.13 will have you winding out.
@wayalife Yep, I just talked to the shop doing my gears. They also recommended 4.88s for my 392. Appreciate the advice and will use it. Love your channel, always solid content.
Burning a little more gas.... bahahahahaha !!!!!
LOL - with prices the way they are, every drop counts.
Agreed! My 2019 JLUR on 37's never went into 8th gear. Switched to 5:13's & has great acceleration & goes into 8th gear easily. I was worried that 5:13's would be too steep, but cruises great on the highway at about 2600 RPM at 75 MPH
Yup, sounds about right to me and the power is fun to have. That said, 2600 rpm at 75 mph is way higher than what I'd prefer to have this Gladiator running at. Of course, that's just me.
2600 is a tad bit too much bud! 75 might be the speed limit in areas you live, but you need to really keep it close to 2300 for gear change and cruise at about 1900,2100. These trucks really hold onto gears on ascends so when going up just keep your foot as still as you can and it’ll stay in gear and get you over the hill. In long ascends I’m in 6th at about 2200 and I ease back into 7th once we’re over the top.
Always go with the lower gear if you’re deciding between 2 gearings. When wheeling - be easy on the pedal
To each their own. From experience having done it both ways, I would tend to disagree. I am a guy who makes a living wheeling his Jeep and yet, I would be the first to admit that most of my time driving is on pavement and on the highway.
@@wayalife exactly. I only built 2 but I’d definitely have gone 5:13 on the jk /. 37’s if I had it over again wouldn’t have cost extra since I put an axle up front to replace the toothpick
What brand of gears are you using?
As I state in the video, we went with Currie.
I just want to add, for my older 2007, with the 3 speed/OD and 3.8, the Rubicon 4 door with stock 32s struggled on the freeway. Once I updated to 35x12.50's it was terrible. I upgraded to 5.13s and it was perfect, better than stock by a few hundred rpms. Absolutely Perfect for the original JKs, I put at least 80K on those gears no issues. I sold that in 22 after I bought my 21 4XE.
I find it interesting with my 21 4XE Sahara with 35's (ARB Air locker, lifted, build out, etc.) and feel zero need to upgrade. The 2.0 has so much torque+Electric I don't even notice the difference. And my fuel, around town with 70 mile trip a week is at 35 MPG, my old 07, I was lucky to get 12 mpg. Oh and for me in AZ, Desert Rat has done all my gearing for the JK and locker for the 4xe. Perfect jobs, no issues.
As I state in the video, the all new 8-speed automatic transmission is totally up to the job of pushing bigger tires and at just 35", I wouldn't bother regearing.
@@wayalife Ya, love your videos! Good info. as always!
This looks like an expensive job. How much FP torque increase for a 3.8? What would this approximately cost parts and labor?
Depends on the shop but typically, you'd be looking at about $2k or so for install, parts and labor. Don't know what the torque increase would be but I suppose it would depend on what tires you're running.
@@wayalife Thanks! Running 35’s 🩵✨
@@boosTiMon for us, we charge $1,820.00 labor for a full regear with master install kits. Also includes a 500 mile inspection and oil change 👍🏼
When are you going to do this to the 392
I really don't want to thrown money at the factory axles. They're good for what they are but I'll install new 1-tons with the right ratio when I can find time to do it.
Eddie what's your thoughts if its a 6 speed manual JL on 35's?
Assuming you got your 6-speed with 3.45 or even 3.73, 4.56 is still what I would recommend with 35s
@wayalife Oh I have the Rubicom with the 4.10's
@amarshall5079 honestly, with 4.10s, I might just stick with what you have. 4.56 will offer an improvement for sure but I don't know if it'd be worth the cost. If you do any towing, plan on going 37s some day or don't mind running on the high side of your RPM at highway speed, 4.88 would be the only thing I'd consider.
Why does changing the tire size in Jscan not help?
That might fix speedometer error but the point of charging differential gears is the increase the final drive ratio-in this case from 4.10:1 to 4:88:1-which will increase torque to drive larger wheels. At the expense of requiring higher engine RPM, as the driveshaft now has to turn 4.88 times to revolve the wheels once instead of 4.1 times. But if you don’t have enough torque, the transmission will use lower gears to compensate. So the higher final drive ratio will allow the transmission to use the higher gears.
As @disphenoidal mentioned, Jscan will only correct your speedometer. New gears with the correct ratio will restore your performance back to stock or better.
What year vehicle is this? My 2024 JTR doesn't have a FAD.
I don't know how that is possible.
I did some looking and see there has been a recent change and it's a real shame that Jeep decided to get rid of FAD on JTR.
@@wayalife I really want to open it up and see if the axle shaft is still two piece with a pinned collar or one piece. Mine front axle also has CV joints instead of cardan joints.
@@wayalife The axle shaft is still two piece with a fork build into the FAD block off plate.
Wow, that's crazy
So what’s the reason for not going to a 5.38? I understand not running it in an 8 speed with 37’s but why not a built 44 on 40’s?
As is shown in the video, the pinion on a 4.88 is considerably smaller than a 4.10. A 5.38 is crazy smaller and as I state in the video, from experience, we have blown it in a 44 pushing 40's and with just a wimpy 3.8L. See video here th-cam.com/video/zqkxVi2D9Ng/w-d-xo.html
4:09 he explains it...
@ZboeC5 Thank you for watching the whole video 👍
@@wayalife It was a good video, I need 4.88s for my Rubicon but these guys are about 2,500 miles too far away.
