Gm Spring Bushing Black

The Energy Suspension GM Spring Bushing Black (part number 3.2101G) is a polyurethane and steel leaf spring bushing kit engineered for GM F-Body and X-Body vehicles from 1967 to 1974. This rear suspension component replaces stock rubber bushings with Energy Suspension's proprietary Hyper-Flex polyurethane formulation, delivering improved suspension response, reduced bushing deflection, and enhanced handling characteristics on multi-leaf spring systems.

Polyurethane bushings maintain their compliance across a wider temperature range than factory rubber while resisting degradation from road salt, UV exposure, and ozone—common failure modes in vintage restoration and long-term storage scenarios. The cadmium-plated steel components resist corrosion, crucial for vehicles exposed to harsh weather or stored in variable climates. Energy Suspension's Hyper-Flex material is engineered to minimize compliance slop while preserving ride comfort, a balance that translates to more predictable chassis behavior during acceleration, braking, and cornering on the street or track.

This bushing kit serves restoration shops, vintage muscle car enthusiasts, and drivers upgrading 1967–1974 Camaros, Firebirds, Novas, and Chevelles. It addresses the common wear pattern where original rubber bushings stiffen, crack, and lose load-carrying capacity over decades, resulting in clunking rear suspension noise, increased play in the axle assembly, and degraded handling. Installation requires no modifications to the leaf spring pack or frame geometry, making it a straightforward upgrade path for owners seeking improved suspension feel without platform redesign.
