Check out what this guy found in his PST rebuild kit!

He found a bag with ES bushings, and a "real" part #, and paid $18 more. Check out the message, it really makes me wonder about PST... whether their stuff is polygraphite or not... and whether ES's "black" bushings have polygraphite in them already.

I have the PST front end kit, and I can teell you that they definently had poly in them. Unfortunantly, one of the tie rod ends they sent me DID NOT have any threads!

I installed all Energy Suspension stuff in the front end of Redraif's car, and there are no squeaks whatsoever. Just use plenty of the supplied lube, and either will be fine. I have used both with good results, though I used PST back in 90 or so when rebuilding my Nova SS...don't know if they're the same quality now or not.

Polyurethane or polygraphite? Was there any part # on the bags? PST claims polygraphite, but gave the guy a bag of energy suspension bushings- which are only supposed to be polyurethane.

I've heard the same thing, LT1, to use a lot of the lube... but I though it interesting that the guy got charged $50 for bushings that he could've bought for $32. If PST plays like that, then I won't bother buying their kit, I'll just buy the bushings for cheaper through Summit!

Correct me if I'm wrong, but doesn't graphite conduct electricity? If so, and if there's a high enough concentration of it in the bushings, reason would have it that you could do an ohm check to determine whether it's in there. Obviously a polyurethane bushing should show an infinite impedance, but if I'm right, maybe the graphite jobs will show some sort of high k-ohm impedance. Then again, maybe not.

not enough graphite. but yes graphite will conduct.

Solid graphite does, not when it's powdered into dust scattered through another material.

That was a very creative testing idea. I thought it was cool.

I kind of tend to think that the supposed benefits of graphite impregnated bushings are anyway.

Hi, I'm the guy that got the bag of ES bushings with a PST sticker on them. If you read the post above you might believe that ES sells the bushings to PST and PST re-disributes them. My question is why do they put the same number on them as the regular poly ones. How would they keep them straight??

Who knows.

From Energy Suspension's Website: "For those applications where component twisting typically occurs, our line of black HYPER-FLEX™ polyurethane products contain graphite. This graphite impregnation delivers a self-lubricated effect, reducing the need to lubricate the components."

How do you figure?

Yet another reason I will go with Performance Suspension Components, they use/sell true american made quality stuff.

What reason is that? They get their polygraphite bushings from Energy Suspension as well.

I went with that company. I think their parts are great. This was after I had speed merchant install my front end last year.





All Performance Suspenion Components. It was a difference between night and day after it was all done.
