If you want a good shock that actually works right, it depends on a lot of different things like weight, total weight and front weight, as 34-40 mentioned shock angle has a lot to do with it too. Also depends on what you want the shock to do as to what the valving in the shock is, how you intend on driving the car, and a lot of other things. Price also becomes a consideration, shocks can run from $30.00 each to $300.00 each depending on how much quality you can afford! I usually gather up all this information about the car, then have a long chat with the shock guys at Speedway as 34-40 suggested. They deal with suspension and shock issues all day long and our current on what's new and most importantly, what works!
