Aluminum GEN-F Front Struts for Camaro/Firebird have a single knob to adjust externally for unmatched suspension control with fast, easy ride height changes (12 settings). On coil-over setups, use with GEN-F Springs. Built with factory and modified small blocks in mind, GEN-F Front Springs for 1993-2002 Camaro/Firebird were designed to be used with GEN-F Shocks. In three spring rates, they fit the factory location at the top and, when combined with GEN-F Shocks, offer superior performance.
