Energy Suspension Hyper-Flex Black Polyurethane Cab Mount Set for 1973-1980 Chevrolet C10 & GMC C15/C1500 (3.4109G)

Fits select 1973-1980 Chevrolet C10 and GMC C15/C1500 2WD 1/2-ton pickup trucks.

Restore the proper body-to-frame alignment of your classic GM truck with the Energy Suspension Hyper-Flex™ polyurethane cab mount set. Original factory rubber mounts are prone to dry-rotting, cracking, and crushing over time, leading to sagging body lines and poor cab-to-bed alignment. While solid aluminum mounts provide rigidity, they often transmit excessive vibration and harshness into the cabin. These polyurethane mounts offer the perfect middle ground, providing the durability needed for demanding use without sacrificing ride quality.

Engineered to replace worn-out OE components, this kit (MPN: 3.4109G) helps restore factory ride height and maintains consistent spacing between the chassis and the body. Many mounts in this set feature integrated zinc-plated steel rings molded directly into the polyurethane for maximum structural integrity and long-term service life.
