If you're buying these for the front of your S10 blazer, DON'T! ! You will regret liking me. Unless you're carrying a lot of weight all the time, you don't need to install spring-loaded front shocks. I bought 4 of these for my 88 S10 Blazer and it bounces really badly when going over bumps and bumps. It's almost dangerous. They're fine for the back if you're towing a trailer, but trust me you don't need them for the front either. Get a pair of good gas shock absorbers for the front.
