Hi, IMHO the problem is the use of air shocks to begin with. I have put them on a couple of my cars, and when even a moderate amount of air is introduced into the shocks the ride gets very bouncy. I don't think air has the damping qualities that the sealed oil or gas shocks do, and I now believe that the air shocks are good for increasing load capacity but not for much else. I would use good quality gas or oil shocks for OEM replacements. Bill Huff He you minority, Anybody know of a source and correct numbers for front and rear shocks. I went to my local NAPA and they sold me a pair of rears that they said were correct. Unfortunately I acted in faith, painted the shocks black and installed. They are air shocks and I noted a much larger diameter. Turns out they are way to stiff and now the car bounces over bumps. Thanks for any help. [Non-text portions of this message have been removed]
