I just got two new ones from my local GM dealership when I installed my Koni/Strano spring setup. I believe they were around $34 each.

They are available through the dealership. I replaced both on my '94 Z28 in May. The originals had dried up and were falling apart.

he said from the start he didn't want the poly ones.
I would hardly consider the poly ones an "upgrade".
that must be a harsh impact. the stock ones are cushioned by design.

I do understand that the poly ones would be good upgrades if you do allot of drag racing. I want to do something like a g-machine set up. I like track racing. So the softer stock ones would be better. Especially going into turns and such. I think that the poly ones would hit to hard....

Thanks everyone. I guess Stearlerships is the way to go..............

I actually run a bump stop on the shock itself in the back...not sure how great of an idea it is, but I needed the clearance for my wheels.

WOW! SLP sold several sets last year for like $2.95 per pair...YES, less than $3 per pair. I bought 3 sets...1 went to a friend, one to use, and now I have a spare set. They were take-offs left over from the Firehawk/SS/WS6 program I guess...

I don't think the original poster would want those - the SLP bump stops were not very progressive (if at all), so when you hit them, it was harsh. The factory Z28 bump stops had more of a triangular shape to them, so they were a little softer on initial impact, and is why a lot of people prefer them over the SLP style bump stops.

The SLP bumpstops I bought were TAKE-OFF and identical to the stock ones I took off of my Z28...it was a foam type material. I'm guessing these were the factory bumpstop SLP removed to put theirs on.

Plus this. Mine were rotted out on my SS. I regret it though because I was driving it not long ago and I ran across a rut on a road and my fender dimpled. This was on a KONI shock also.

Mine were falling apart on my 01 formula so I stopped by a local salvage yard and found that all the 4th gens there had the bump stops broken off. I decided to look at the third gens and they were all intact, so I compared the two and they mount the same. I guess the ones used on the third gen f bodies were made from a more durable material.
