Energy Suspension motor mount inserts for 1963–1972 Chevrolet C10 pickups are made from Hyper-Flex performance polyurethane and are intended to replace soft OEM rubber mounts for improved durability. They’re engineered to run softer than metal mounts for street use yet remain rugged for performance applications, resist oils and road contaminants, and provide longer service life compared with original rubber components.
