Product Description

The Ridetech 11534899 Complete Kit replaces the factory single-leaf rear spring on 1963-1982 Corvettes with a 9-leaf steel design rated at 175 lb./in., stepping up to 225 lb./in. once the overload leafs engage. This cuts body roll noticeably while keeping a comfortable ride, and the included side shims handle both leaf spring widths used across the C2/C3 production run.

Unlike the leaf-only version, this kit adds everything needed to also lower the car: stainless steel bolts, polyurethane bushings, and aluminum spacers that set a 1"-2" drop. It's a one-box solution for C2/C3 owners upgrading the rear spring and dialing in stance at the same time.
