Poly bushings

[msggunny]

Anyone here running poly versus the rubber OEM kind?

What do you think of them? Any wear issues?

Thanks.

Poly Pro's:

look cool
usually easier to install
less play then the stock rubber

Cons
Wear out faster then the stock rubber
usually cost more then stock rubber


For a series truck I think the stuck rubber is a better way to go given that there are series trucks with 40 year old bushings that are still ok. I have run poly shock bushings in several cars and they need replacing about every 5 years with regular driving use. If you are building a race truck or performance vehicle then the poly will be a good choice.

I dont know about the longevity of the stock ones. The ones in my springs are shot and only have about 10-15K on them.

I think the real question is, "are current available rubber bushings nearly as good as those fitted by the factory 40+ years ago?"

I don't have any personal experience with new rubber bushings failing, but I read that they do so prematurely. For that reason I'm leaning toward greasable poly's next time around.

I, too, have the GBR greasable frame bushings. They are the cat's whiskers, IMO. Took me minutes to install (after I destroyed my DNA when burning out the old rubber ones).

Since they are greaseable I expect them to last longer than the ungreasable ones.

As others have said, I would rather replace the polys a dozen times than replace the oe bushings once.
