I own a 2020 JLUR still in stock form. I know there is proper gearing for different tire sizes. And 4:10 Gears and 37’s although ok, is not ideal. That’s all I mean.Sorry I ran 37s for a year and it was great. Ran 38s for 6 months with no problem before I regeared to 5:13s. By your response I would say you don't have a Rubicon and you've never had 37s on one. Thanks.
Did you re-gear and, if so, what ratio?I was the second poster to this original thread in 2018. After reading here and doing my research, I installed 37" BFG KO2's on KMD Rockstar wheels along with a Mopar 2" inch lift kit. I also replaced the front and read bumpers and when doing so, I removed the small section at the bottom rear of the back wheel wells that connected to the rear bumper.
I've never had a single rubbing issue and I wouldn't trade my 37's for anything, except maybe 40's (who says size doesn't matter). I've had so many positive comments about my Jeep on 37's and I've also driven for twelve hours straight at highways speeds (+ 85 mph in 8th gear).
I did install a set of Rock slide Engineering drop down step/sliders to deal with the increased entry height for my wife and granddaughter and frankly it helps me too. I love the look and driving feel of the JLUR on 37's.
By the way, the spare is being remounted this weekend using the Mopar hinge reinforcement kit (already owned it from original purchase) and the Teraflex HD spare tire carrier kit, along with the Artec license plate mounting kit with the Off Road Only license plate lighting kit. More pics after the install.
Nope, no re-gearing necessary. I can still see the Jeep in 8th gear on the highway, so I personally don't see the need. There are many voices on the forum that will disagree but I have zero performance issues with 37's and a two inch Mopar lift.Did you re-gear and, if so, what ratio?
With regards to your shocks, I went with RK’s RRD shocks (got the Adventure Series 2.5” Stage 1 kit). Figured I’d keep the springs mated with the same manufacturer’s shocks.This is a great thread with lots of fantastic info. Y’all. have pushed me over the edge for getting 37s. But I do have a couple basic questions.
I’m going to go with a Rock Krawler 2.5” Max Travel “No limits” lift. I just need to decide on shocks (not decided on RTTs yet). But I’m also planning to use the base Rubicon 17x7.5” wheels. Do you folks know if I need to use spacers or will this work just fine with no rubbing? Please note that I absolutely off road my vehicles and I plan to be in max flex situations.
