- 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.

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 👍
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.
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.
So good to see a new video guys!
Happy to hear you enjoy our videos 😎
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
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.
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.
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
Maybe I missed it, did you change the front gears as well?
You missed it. See video from here ua-cam.com/video/bNlCEE3Xwj4/v-deo.html
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.
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 ua-cam.com/video/zqkxVi2D9Ng/v-deo.html
4:09 he explains it...
@ZboeC5 Thank you for watching the whole video 👍
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 😎
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.
