When I first received it, I thought it may have been for a bigger SUV or even for a large pick up or dually. It looked like it had more coils on it and felt really heavy. I took these coils to my mechanic and he also had similar reaction. When he took the old (GM) original springs out they looked nothing like Moog ones, the were lot lighter and had less coils in them. So I was worried that I received the wrong springs but mechanic had no problem installing the new Moog ones and they were precise fit. The ride got much better and I was really impressed. Wish Moog made quick struts because i know they would be of great quality, I won't even look else where
