I have a set of OEM Z71 Bilsteins off a 97 1500. They have around 20,000 miles on them. I bought them from a friend to put on my old truck, because I couldn't spring for a new set. Especially considering I wasn't sure if I'd keep it.
I didn't keep it. And now I have these shocks. They are in good condition.
$50 Plus shipping which will be around $10 to pretty much everywhere.
