GM BODY MOUNT SET

The GM BODY MOUNT SET from Energy Suspension is a complete polyurethane bushing kit engineered to replace worn factory rubber mounts on GM A-Body vehicles from 1965 to 1967. Body mount bushings absorb vibration and noise transmitted from the frame to the chassis, and OEM rubber compounds degrade over decades, allowing excessive movement and harshness. This Hyper-Flex polyurethane replacement set restores structural rigidity while eliminating the suspension slop that accumulates in classic muscle cars and street machines, making it essential for anyone serious about handling and NVH control on vintage Chevrolet platforms.

Energy Suspension's Hyper-Flex polyurethane compound is significantly harder than original rubber, reducing deflection under load while maintaining progressive compliance to isolate drivetrain vibration. The set features steel-backed polyurethane bushings with cadmium-plated hardware, designed to withstand the chemical exposure and temperature cycling common in engine bays and underbody mounting points. Polyurethane does not dry rot, crack, or sag like aged rubber—properties that make it the preferred material for restoration and performance applications where durability and consistent geometry matter. The red color aids visual identification during installation and inspection, and the complete kit consolidates all mounting points in one purchase rather than sourcing individual bushings.

This kit is ideal for owners restoring 1965–1967 GM A-Body vehicles—Chevelle, Malibu, El Camino, and related platform cars—who want to improve structural feel without modifying the chassis. Installation requires removing the body from the frame or selective access from underneath, a task well within reach of home mechanics with basic suspension experience. Because polyurethane is slightly stiffer than OEM rubber, some users report a firmer ride quality and reduced body roll during cornering; this is normal and typically considered a benefit in classic car handling. Verify fitment against your specific model year and confirm frame configuration before ordering, as early A-Body geometry varies by year and engine choice.
