Jkur Hard Rock, 37" tires and keep full bumper and fenders?
I've seen it done but would like some advice. I have a 2016 JKUR Hard Rock. I'm thinking about going with some 37x12.50x17 mastercraft mxt's, but I want to keep my full bumper and the full stock fenders. Will 4.5" backspacing work? What lift height should I be looking for? I'm thinking about going with the Mopar 4" with some extra pieces for the front to get the geometry right. I'm not planning on wheeling it much and I'm in FL so no rocks to crawl. Thanks in advance for any helpful advice.

Be sure to trim your rear pinch seams. I have a buddy that has a slash in his tread because the pinch seams were not trimmed. As for the front I would go with it to see if there will be any rubbing in full stuff. Where you run into rubbing is when turning sharp left or right in full stuff due to the largest part of the thread is the wheel well.
4.5 inch backspacing should be fine.

2016 rear pinch seams are already trimmed from the factory. I got mine with 11 miles on it and the seam is trimmed. I have 37's and MC Gamechager 3.5 running 4" back spacing and 1.5" spacers. Not sure about the mopar lift, but MC says 3.5-4" backspacing for no rubs.

Probably. I am running JCR rock rails, they are way short and out of the way. A few of the guys I ride with have rubi rails that are trimmed, its easy. Be careful with the end caps and you can reuse them.

Pinch seams have been trimmer since '12 or '13 from the factory from memory. I am running a RK 3.5" with 37's and 3.5" BS and have no rubbing on the frame at full turn and flex. I would say 4" BS is the minimum you'd want to run to have no rubbing on the frame in the front. 4+" of lift if you want to keep uptravel without 5 inches of bumpstop to stay out of the flares. I have 3" bumpstops, cut flares, and I'm resting on the flare support in this pic. You'd want at least another inch of bumpstop or not 2 to stay out of the flare.
