    I have a 2017 JKU with the Dana 44 rear axle and the Dana 30 front axle. I recently went up in tire size from the factory 265/70/17's to a set of 285/70/17's (both sizes are BFG K02's). The Jeep still has the factory 3.21 gearing. It has been okay for flat ground and some small hills but shows...

    So I'm finally regearing from my 3.73's (which I didn't want but came with the auto trans option) on my 2015 Rubi Dana 44's to something more... robust. I'm on the fence between 4.56's and 4.88's but leaning towards the 4.88's. I'm currently running 35x12.5/R17 BFG All Terrain KO2's on 17"...

    I had my Jeep JKU sport re-geared to 4.56 after having 35’s put on. Also have swapped out the driveshafts with some 1310s front and rear from adams. After getting the Jeep back I noticed I’m getting a humming almost vibration like sound after hitting past 30mph and ONLY when the gas pedal is...
  5. YJ Technical Discussion
    I'm regearing my 1994 2.5L YJ from 4.10 to 4.88. I'm running 33"x12.5"x15' tires. Trail riding and lower gears are fine, but 4th and 5th gear are weak (OK, 5th is pretty much useless). Trying to regain some "pep" in the 4th and 5th gears. So I bought the Yukon Master Kit for the Dana 30...

    I am a new jeep owner (roughly 1 year) and have a 2019 unlimited sahara JL with the stock wheels. I have a picture attached. I'm looking to get a 3.5 inch lift and 37 inch tires. I don't like the look of 35s as much and know if I get them now I'm gonna want to upgrade again, so might as well...

    I recently got 35s on my 2012 JKU sport. It’s got the 3.21 gears and honestly it handles it way better then would have guessed but I can definitely fell the power difference and see the gas mileage difference. I’m going on vacation in August and will be traveling a good distance with a lot of...

    I'm going to jump into regearing my Jeep by a shop and want to know what is the best jump between two gear sets. First my rig is a daily driver that I take on long road trips in California with my wife and son and occasionally take my in-laws out of the house with. I love driving it so I...

    As from some of my posts could be deduced, I'm thinkin of regearing my Jeep. Or having it regeared. I would very much appreciate if those of you who've done it youselves would share your experiences here. Good or bad. Especially bad, if you are brave enough to admit failure or defeat in public...

    Hi all, I currently have a stock 2016 Jeep Wrangler Unlimited and was planning on doing my first build. I've been spending the past couple weeks on learning about the components that are involved in getting a lift. I had a couple questions but also wanted to just lay out my plan with links for...

    I just got my Jeep back from the shop after having my diff regeared (Yukon gears). Now I'm hearing a sort of high pitched metallic rattling sounds (see attached video clip): Is this normal? Will it go away with break-in or should I take it back?

    Hello! I recently began taking my 3.73 Dana 44 to 4.88. I'm a heavy equipment mechanic but man these gears are a different breed. Would anyone be able to translate this tooth pattern? I'm having trouble figuring out what adjustments to make. Thank you

    Looking at regearing options and what benefit I will get out of it. I added a 2.5" lift in 2018 and changed my tires from 32" (255/75/17) to 33" (285/70/17). The standard gear ratio for my 2010 JK is 3.73 and it's been suggested that going to a 4.11 would improve my power and performance...

    Hi Folks, Considering re-gearing my '16 JKU. Are there any NJ enthusiasts that can recommend a shop? I'm in Union County, but don't mind some travel. I keep the Jeep in MA out on Cape Cod, so I'd also be interested in any shops in eastern MA (Barnstable county) as an alternative. Thanks in...

    First post! So I put a Mopar lift on my 2.0L JLU, geared 3.45, and went from 31's to 35's. Now the Jeep waits longer to shift up after having made it up to speed. Also, while going uphill it will sometimes shift down making the RPMs jump considerably higher than it did before, almost as if...

    For a bit of background, I have a manual transmission ‘08 JK with 33” tires, a 3.5” suspension lift, and stock gears. I am looking to upgrade to 35” tires. Over the past two years, I noticed that my Jeep does not perform well on the highway. I was expecting that, but not to this degree. When...

    Hi all, I purchased my first jeep a few months back and have been enjoying both working on it and driving it a ton! I made a big mistake of not doing my part studying about what was all needed in a 4x4 vehicle, etc when I bought it. I think i just got more excited than anything. Well onto my...
