I have the rock krawler 3.5 X factor and my rear track bar is bottoming out on my bump stop on passenger side has anyone else had this problem.

 

Can you post a picture so we can see what is happening?

 

if the bumpstop extensions are anything like teraflex's, they extend forward from the axle to allow users to push their rear axle back and still retain a proper bumpstop pad. You may have them on backwards

 

Rotate the track bar back a little bit.

 

The track bar mounting location is hitting the bump stop bad. So rotating the track bar will not help. I do have teraflex bump stops that extend forward.

 

Are your arms adjusted to the correct lenght? I installed a buddy of mines lift, and his trackbar bolt was coming in contact with the bumpstops. We were able to trim the bumpstops to clear(His stops were steel.)
I recently installed another guys 3.5 X-Factor kit on a 4dr, and didn't have that issue at all when arms were adjusted to RK specs.

 

Is your pinion rotated? I had to trim my bump stop a bit and reverse the track bar bolt to fix mine.

 

Yes, I have seen that exact problem with the rock krawler kit. Made a new track bar bracket for a couple of people to solve the problem.

 

when I installed the lift I used the measure man for the adjustable control arms. And it moved the axle back and rotated it. But seems if I didn't have bump stops at all the track bar bracket would still contact the bump stop pad on axle. I would post a picture but the iphone app is jacked up lol

 

You try loosening both jam nuts and rotating the track bar away a little ?

I've also seen a few people double shear the frame side mount.
