If choosing a brand of shock that we have not provided a part number for, match

(We can not ensure that the valving profile in your shock choice will pair well with
our kits. This is why we recommend using our RRD Racing shocks or the provided
Bilstein part numbers)

Generic Rear Shock 
Recommendation with 2 " bump stops -16" Collapsed to 26" Extended
