2006 WK - Suggestions for Extended Bump Stops in Rear?

I recently installed an OME HD Spring and Shock lift, and fitted 33" tires (285/70/17). This set up is working pretty well, especially up front, but a recent shake down trail run demonstrated that the rear tires rub significantly.

It's rubbing at forward side (9pm on a clock when looking at drivers side), right at the rear door. I don't think just rolling the fender is going to fix this, and I don't want to cut it because it will literally leave a gap at the door seal.

So I am thinking that extended bump stops are the way to go. I am quite confident I am not the first to have this issue, but I while I have seen multiple threads that confirm bump stops are needed, I have not found a thread that suggests what to use or how to mount them.

So that's my question: What extended bump stops have worked well, and how are they mounted?

I had these from Timbren. They are expensive, but work great. https://timbren.com/i-30497866-timbr...R%20SUSPENSION

I took the bumpstops out on mine because I instead installed load adjusting shocks. There's pretty much no way my tires will ever hit my fenders unless I have some incredibly heavy weight on the back.

I think the correct way to fix this is with adjustable rear control arms to center the rear axle. Check out omelets build https://www.jeepforum.com/forum/f67/...bison-1309254/

Honestly, on the cheap... a hockey puck bolted to the center of the spring perch. I countersunk the hole in the puck so the bolt head is flush with the top of the puck.

Longer control arms will help but induce other problems dependent on how far away you go... Namely, you only have so much room before you start causing problems with your track bar. I ended up welding some rectangular tubing that perfectly fit the track bar inside of it and welded this to the back side of the track bar mount, effectively pushing it back 1.5" to match the 1.5" I went back with the axle. The spring was hitting the track bar mount. I bent the front side back after moving the arm to the back side of the mount. It looks ugly as hell with a piece of rectangular tubing stuck on this nice shaped bracket. But it gets the job done for now and I have other plans for the axle back there. Ill fix that when I do all of that.

I lowered my factory bump stops by having a fab shop cut with plasma table some 3/4 plate( basically made two 3/4 thick washers), and sourced longer (M12 I believe) bolts at hardware store. I am running 255/75-17s(32), and have 1 tire clearance at full compression. If you are running 33 tires, and 3 of lift these bump stops may not help where you are rubbing. Iron Rock Off Road sells Adjustable LCAs( they are listed under WJ Grand Cherokees), but after measuring a friends new pair they will fit a WK. I am ordering a pair to correct pinion angle issues, and seeing that my pinion angle requires rolling diff downwards to correct it will provide to some degree re-centering hub/axle in wheel opening. Hope this might help.

My apologies, I owe this thread an update. I have NOT installed new/longer LCA's for the rear as of yet. However, I did figure out the extended bump stop assembly. A while back I posted this thread seeking info on the bolt that goes into the bumpstop receiver cup. It's an M10x1.5 Course Thread. I replaced it with a M10x70 Course thread extended length bolt.

I purchased JKS billet aluminum spacers, but didn't realize they are not shipped as a set, so I drilled out a pair of hockey pucks ($2 ea at PlayItAgain Sports), insert them between the frame and the receiver cup, and then installed Metal Cloak's progressive foam bumpstops. I did a write up and photos on that other Jeep site, where you park your Jeep inside [thread title: "Jeep WK tire fitting"].... While in there, I also rolled the rear fenders, which I think will help quite a bit. That is included in that thread on the other site.

I haven't had a chance to really flex it out out on the trail yet. Hopefully this weekend.
