Let me take another second to clear up more confusion.
There is only 2 lengths of control arms offered on a factory Jeep. This might mean nothing to you. But it will as you drive. The lower CA and Upper CA is how your axle attaches to your frame. They are attached behind the front axle and run back to the frame and are attached vice versa on the rear. They are fixed length. So as lift increases the front axle move backwards and back axle moves forward. And If you lift too much without lengthening the control arms your axles can and will touch the fenders/liner. It shortens your wheel base and make your steering more flighty. So from the factory, Jeep only lifts at most 2” for any of the JLs. Otherwise it brings in a world of other changes. And when you add lift to any 392, you really need to add longer control arms, lower and upper. If you don’t, that is when you see people complain about wandering and jumpy and flighty steering. Those Jeeps have very little caster. Just adding LCAs without uppers it will increase caster but lower pinion, which binds your driveshafts.
Secondly, to put 35s on any trim/engine level of jeep, they had to decrease articulation so the taller tires don’t rub when stuffed. So you will see on an XR, more bump stop front and back then a non XR. And you will feel that bump stop off road as the tire stuffs up into the well.
I hope this helps.
