For early design Pro small body smooth aluminum shocks that have retaining clip groove, for 1-7/8" I.D. springs. 4" in length. SBA shocks are 1.63".
Note: Current Pro small body smooth aluminum shocks do not have the retaining clip groove and therefore are a non-coilover design shock.
If a coil-over shock is required, a threaded body shock must be used in conjunction with coil-over kit #'s 582-C330 for 1 7/8" springs or 582-C335 for 2 1/2" springs.
