Clearance Issues w/37's

I have a '13 JKR with a 2.5" AEV lift and trimmed Rubicon rock rails along with the pinch seam. Over the weekend I put on a new set of Nitto Trail Grapplers in 37/12.50/17 and get quite a bit of rubbing on the front of the rear wheel wells. If I remember correctly a fix might be to install rear upper adjustable control arms which would pivot the differential rearward an inch or so and make the pinion angle much more acceptable while giving me the clearance I need. I also recall the pinion angle is much more of an issue on this two door vs. the four doors.

Thoughts?

You are too low for 37's. Flat fenders and extended bumpstops are needed if you want to stay with LCOG.

what he said. i have the same size lift as you but have 2.5 inch extended bumpstops in the rear that came with my kit (teraflex). i also cut my fenders. They are both required if you ask me. im also putting in a 1 inch body lift this week. also you will have to do some trimming to the front and rear pinch seam. max out your suspension and see where it hits

Yea I have flat fenders and 2.5" bump stops already. The rear axle in its stock location is just too far forward and hits far more of the pinch seam than can be removed. I know it is fairly common to use 37s with 2.5" lifts and flat fenders with bumps tops but there is far too much room in the rear of the fender well that needs to be used. I'm looking for info on why people use upper vs. lower adjustable control arms and if it was to gain clearance.

Take a pic of your rig with the 37's. The pic with 35s are of no help. I have put adjustable control arms on the missus 09 JK. She is running a 4.5" lift though so they were needed. Not sure why you'd need them with 2.5". Hence the pic request.

I'm working for a couple days so I won't be able to take pictures for a bit. I just seem to remember reading some time back that the first step for new control arms were front lowers and rear uppers to correct pinion angle and wheel well clearance issues. Can't remember for sure, maybe it was rear lowers? So why do people replace any rear control arms if not for pinion or clearance issues? Does it need to be all four or uppers or lowers?

If you wantr to move the entire rear axle back towards the rear of the fender well you will need both upper and lower rear control arms. getting just the uppers you will only be able to adjust pinion angle. Are you sure you cant trim anymore? I trimmed mine all the way to where the pinch seam ends and am not rubbing. I am also using a 1.25 bl
