GM CAB MOUNT SET

The GM cab mount set from Energy Suspension is a polyurethane body mount bushing replacement engineered for full-size GM trucks from 1973 to 1980. If you've owned a classic truck long enough, you know that factory rubber cab mounts deteriorate, allowing excessive chassis flex, cabin noise, and unwanted vibration transfer from the frame to the driver. This cab mount kit addresses that problem with a engineered upgrade that restores structural rigidity while improving ride quality and NVH (noise, vibration, harshness) isolation.

Built from Hyper-Flex polyurethane with steel hardware and cadmium plating, the GM cab mount set combines durability with controlled compliance. Polyurethane bushings outperform factory rubber by resisting oil degradation, UV exposure, and thermal cycling—critical factors in vintage truck restoration. The red color makes installation straightforward for visual verification. Hyper-Flex formulation balances stiffness (reducing cabin movement during acceleration and braking) with damping (preventing harsh road shock transmission), making it ideal for both daily drivers and weekend warriors seeking a balanced suspension upgrade without sacrificing comfort.

Mechanics and truck enthusiasts restoring C10, K10, and other full-size GM trucks (1973–1980) benefit from this complete cab mount kit, which eliminates the need to source individual bushings from multiple suppliers. Installation requires lifting the cab to access all mounting points; an experienced technician can complete the swap in 2–3 hours. Once installed, you'll notice reduced vertical movement over bumps, tighter steering feel, and audibly quieter cabin operation. This kit pairs well with frame stiffening, new suspension bushings, and powertrain mounts for a comprehensive drivetrain isolation upgrade.
