My JLR is running the Mopar Lift with 37s, on the road there is no rubbing, offroading I do get some rubbing at certain angles in the front wheel wells but I really don't care.

Mopar Lift with 37s using stock wheels and 1.5” spacer. Definitely rub off road at full flex in the rear and up front. I’m going to try a 1.75 spacer and clearance the inner fenders a bit.

Yes, it's a Rubicon with the 2" Mopar lift. I guess I can always try it out, and make further modifications if I run into rubbing issues. I'm already running 35s by the way.

Another somewhat related question. Will the stock wheel offset also work with 37s? I was hoping to use my stock wheels and run 12.5" wide 37s.
You don’t need anything on top of 2” Mopar lift especially for gasser jeep. I have it on my Rubicon diesel and experience slight rubbing on extreme articulation. Diesel version was nor available for a long time so I installed 3.6L version. I am deciding between upgrading to diesel version of 2” Mopar lift for around $1,300.00 or removing fender liners and install American Adventure lab fender mod an inner fenders. Not sure what I end up with.

No need for more lift than what the Mopar gives you. 2” is plenty for 37s. And all 37s have differences but there is no true to size 37 except for MTR or Interco’s might be close. No other tires are even close to measuring 37” tall. A 37 is a 37. Pick one and move on. You can easily run them on stock wheels. I run them with no spacers, and with the correct bumpstops and adjusting the steering stops a few turns, you can get away with it just fine.

good luck and enjoy.

I thought on a rubi you can run 37s with the mopar lift. If not, getting high fenders seems to me a better alternative than spacers.

You can just fine on a Rubi. You’ll still need wheels spacers to run 37s on a sport with high fenders. The axles aren’t wide enough to run stock wheels.

That's helpful, thank you. I'm going to give it a shot. Have any recommendations for a set of bump stops?

I’m just running the Mopar kit stops but I know a few manufacturers make some stackable, adjustable ones that work fine. Synergy, Teraflex etc. Most lift kits come with them. It all depends on which kit you go with.

Find a good place to flex it out and turn wheel in each direction, at differing angles and adjust steering stops as necessary. Same with bumpstops but I’m sure most BS that come with the kit will be sufficient. A few pics. The first two are of my 4 door JL on factory wheels on 37s. My 2 door is the same. Just a picture of how far I adjusted the steering stops. It was with the RC spacer lift.

Thanks for the pics! This helps a lot. As far as the bump stops go, I already went with the Mopar lift, which came with bump stops, so I guess I'm covered there. I just didn't know if you were suggesting I would need more of I went with 37s, but it sounds like I should be good.

I concur with OnlyOne's post. For over a year and 12,00 miles I have been running a Mopar lift and 36.77" (37x12.5r 17)Cooper STT Pro's on AEV JL Pintler 8.5x17 wheels( 5.77 BS and +25 offset). My JLR is pretty heavy at 5,200 lbs. but Mopars lift is still more than 2.5 inches. At full compression rear tires where rubbing the inner liner at the rear bump outs. I used a heat gun and reformed them flat, issue resolved. In the front the tires where rubbing the Synergy LCA's. I turned out the steering stops 1/4" and that solved that. I have noticed a very, very slight seldom rub mark on the upper inside of the front liner. Other than monitor during tire rotations, I'm finding no other actions are required. If a shorter 37 tire was chosen these front issues might no happen. BFG's A/T's are short for example. Wheel width also plays a roll in tire diameter. I personlly would not mount a 12.5 on a 7.5 wheel and it isn't recomemded BTW.

Not to bump an older post but ive been looking for someone else besides myself with a JL with a body lift. I fit 37”s stock on my sport but rubbed a bit in the rear on bumps. Running a 1.25” body lift to help clear the tires. My suspension lift finally came in (5 months later) and is being installed today. Will see how it looks..
