I have to confess 22 pages is a lot to read and since it is a pretty old thread what may have happened in the beginning may no longer be true.
This thread is so old it has gotten at least 1 post every day, sometimes over 20....
everthing in it still stands, no aftermarket part has been put into production that doesn't require a minimum of 2" extension, so, if your front shocks are less than 15.5" collapsed length, and you don't have 2" extensions, the bars will make contact during susension compression, it prematurely wears out hiems and or breaks them, even the 22mm Tre's don't survive repeated beatings. it doesn't matter if the bar is solid, what good is the 3/4" hiem in the end of it when it's scrubbing the cover adjusted out half way, the bar will flex and the threads will eventually bend and/or break.
I've already put the challenge out, I realize I'm just a NOBODY, but I at least check every thing in an unhurried meticulous manner with the springs removed before I call it good, If RC, JKS, Currie, Iron Rock, RE, BDS, or anyone I left out has one that fits with less than 2" bumpstop extension, I havent' seen it yet,
I will say JKS has one that fits with 1.5" extension and also clears a Riddler cover, I do not know the specific part# BUT if you run high steer, flipped TRE, or less than 1.5" extension it will flex the Tie Rod out as it passes and get hooked on it. I know this simply because one was sent to me and I tried it's fittment.
The other major complaint I have about aftermarket bars is the polly bushings. They may be fine for a street car you don't want flexing, but used on a jeep track bar or control arms where Flexibility is the goal, they wear out very fast and can harm the brackets and bolts. there is nothing better than factory molded rubber bushings in that application.
