Holy crap! It's the living dead! Been a while Corpse... nice to see you post again. You ask an excellent question too...corpse said:I am curious - is this an urban legend, or is PST simply lying about not know of any failures, or do you know of any personal cases where you witnessed/experienced the breakage? I'd imagine if their polygraphite was used and caused failure, they would hear about it. But of course, many companies would lie about something unless the public had major proof.
I asked them about it only because I put their bushing in there, which had/has me concerned a bit, and they said they never heard of a failure.
I never hear of complaints of TCP's strut rods breaking, and theirs are hard mounted? Or does the breakage occur when the polygraphite encourages the strut rod to bind during suspension travel? Which I know wouldn't be an issue with the TCP strut rod as I think their is on a heims end to allow swivel.
One thing that makes me less worried with my car - my front suspension is stiff and lowered, and doesn't travel a whole bunch - so my thinking is, less chance of binding..

I don't really think there is much out there on the urethane market that isn't graphite impregnated these days.
GAT, PST... They both have imported metal for the arms. Go with Moog and buy the bushings separate. For the uppers, Maier Racing makes the best US made stamped ones i've seen...

Who sells Moog stuff?

mdjay said:I think this is more of a failure issue with relation to metal fatigue. I have directly seen them brake but I have seen many hold up as well.
The hard mounted TCP and GW ones won't fail because they're much stronger than stock strut rods. The issue with these aftermarket ones is the bracket you are mounting it to can fail if not re-inforced.....................................................................................................................

Polygraphite is not a real word, just a trademarked buzz word!
Maier sells the lowers as well.

Any adj. strutt rod is far better than a stock style strutt rod. The bearing in the front does a great job of making the car feel better and be safer to drive in my opinion.
