I just called Performance Products, and they will replace a leaky shock I bought in 1999! Now, that's customer service by Bilstein.

And to add more praise to Bilstein, I climbed in the attic and grabbed the original 1990 shocks that I had saved, and bolted them on. They seem to ride just fine. I took them off at 100k and threw them in the attic, just assumed they had to be getting soft by then.

WOW,
DG
