RK rear trackbar bracket hitting shock

I have the 3.5" x-factor kit and the rear trackbar bracket is making contact with my Bilstein 5100 shock at full stuff.

I thought it looked a little close at install, and when I test flexed it confirmed it.

Has anyone else had this problem? How did you correct it?

It hasn't made a dent or gouge yet, just scuffed the side.

I centered the axles under the jeep so we can rule out the possibility of that being the cause.

I may not have enough knowledge on this, but the shock mount and the tb bracket are 2 fixed points on the axle tube and a fixed point up in the frame for the shock. My thinking is that possibly the tb bracket bolts or shock bolts could be loose giving some play in the shock as a whole or the bracket is shifting.

I finally ditched that "other" forum

Everything is bolted solid. I was planning on welding the tb bracket in a few days, now im not sure i will keep it.

Mine is/was doing the same thing. Only happens to me when I am at extreme angles with the driver at the top of the angle. Might want to check your pinion angle and make sure the rear axle isn't rotated too far back. Don't think mine has hit since rotating the axle forward. One of the things I have to check today, got back late last night from wheeling through some tight off camber stuff.

Post us up a pick of your pinion angle where the rear DS meets the differential.

Question for ya, cause I have the same set up. Look at your passenger rear behind the tire, should be a bracket that mounts to the frame, see if the bolt on that side is hitting the bracket bolted to the frame.

I have my pinion rotated so it's parallel with the shaft. I'm running a double cardon Tatton, it must be in that position to eliminate vibration.

And for your question, I just walked outside and took a look. It looks like the upper trackbar bolt makes contact with the teraflex bumpstop. I havent noticed that until you pointed it out.

Today I'm going to head out and do some more test flexing. I'll take photos of the points of contract.

Thanks for the help so far everyone.

With your pics, contact RK, email them the pics. They are extremely helpful in getting the suspension dialed in. My rep was Jeremy, top notch support.

As for the bolt contact, trim it off. What I am going to do and what RK suggested. Don't know why I didn't have it done when it was at the shop and on the rack. Mine barely hits now that the axle has been rotated forward so hoping the triming eliminates any future contact.

What were your results?

I cut the bolt end off yesterday and repainted behind the bump stop where the bolt hit. Will check next time out if there was contact.

Didn't get into that yesterday. While under there I discovered a leak coming from the tailshaft on my transfercase! It's always something, but that's the fun of building a jeep...... right?

I have the king 2.5" shocks with the RK rear track bar bracket and had to cut the corner of the bracket all the way down to the stock bracket and weld it to get the room for the larger shocks! With the bilstien's you probably don't have to go as far as I did and can get away with a little grinding to the bracket to get some more shock clearance?
