Hey all, does anyone have the Bilstein part numbers for the 4 shocks and the axle damper? I don't want to go as crazy a QA1's. Also, if anyone has used the Bel Tech shocks, are they any good on our trucks? I had them on a lowered truck years ago and they were great, but these are a different beast. Any other real world experience with other shocks and recommendations would be helpful.
