I've head a lot of complaining that the SJ
trackbar is a bad design.
I have the RE1600
Trackbar on my XJ and it works well. My only complaint is the frame end joint wears quickly. If I could do it over again I would go with one that uses standard bushings, even if it didn't flex quite as well as it is pretty frustrating when a joint doesn't even make it a year before it starts popping :?
