Bump steer after 4.5" Rubicon Express SuperFlex
Had the 4" rancho with jks track bar and factory drag link. Now that I have all rubicon express it's got way more response through the steering and every little bump or dip the wheel turns. Not what I was expecting from this lift. My track bar drag link angles look pretty close to perfect as they can get.. What gives? Everything's torqued and tightened down, wheels straight. What am I missing? It's got the rubicon express track bar drop, and the chromoly drag link and adjustable track bar from RE.

Before pulling out the credit card and throwing parts at it, you might try to figure out the problem first. Maybe spend a little time going through Planmans big deathwobble writeup? (stuck right to the top of the Write-Ups area). And then you might research the axle side brackets a bit more. Synergy redesigned their trackbar specifically so that it would work with their flip, and there are clearance issues with some other mfg's trackbars. Is yours one of them?

I have the same lift, and yes the drag link should be flipped, my steering wheel was sensitive to the road as well, UNTIL my fix ATS steering stabilizer came in, now it's perfect. I also added 1" coil spacers for total 5.5" of lift, this lift handles my heavy jeep on 40's like a dream. Only thing I dislike is the creaking noises from the frame mounted drop bracket for the track bar. It'll be gone after I install my Artec armor kit which has a raised track bar mount for the axle side.

You didn't answer about the flip and alignment. Do you have the alignment specs? Is your drag link up on top of the knuckle now? Generally, when you reposition the trackbar, you also reposition the drag link at the same time. It sounds like you dropped the trackbar, but you did not move the drag link. is this correct?

OP, I dont like the concept of a bolt on bracket personally, so I'd recommend the Artec raised bracket. 1/4" plate that will work with any trackbar.
