I ordered a set of ES9000's but they came missing many small parts, which cause much cussing, torching, pounding, and time to make work. And that was just the first one. The second front shock was defective, instead of expanding it would just lay there at whatever length you set it. I ended up driving to Sears on three shocks, got a set of Sensa Tracs installed for $200, and sent the Pro Comps back for a refund. The mail order place didn't even argue about it.
