Depends on the bump stop extensions included with that specific lift. Do you know if that exact lift has this issue?the 37's will rub the rear inner fenders at full flex at 2.5". not a big deal and easy fix with a heatgun. im gettting the RK 3.5" to avoid it myself on my 2019.
If you plan on wheeling your rig and anticipate getting full flexed, I would recommend getting rid of your rear inner fenders and replace with artec or dv8, because you’re going to rub, I did and I’m at 3.5”. You can use longer bump stops but I didn’t want to restrict my flexibility. They recommend 2” bump stops for 37” tires with that kit, also a rim with 4.5 “ backspace is also recommended. You shouldn’t have any problem in the front, the rubi’s high line fenders really help. Here’s pic.Looking to put on 2.5” rock Kralwer X factor lift with Mickey Thompson 37”s. Any issues with this on a 2019 JLUR?
