1980 GMC C1500 Transmission Parts

A true performance application component for cars, trucks, hot rods, racing/competition, yet popularly used for street vehicles when more horsepower is added. Soft running enough to absorb vibrations for street use yet rugged for racing use. Helps control torque on high performance vehicles. Maintains proper drive shaft angle to help prevent early wear and unexpected power train damage. Replaces the original, short lived and typically too-soft rubber mounts and outdates those hard-running metal transmission mounts. Resistant to under vehicle fluid oils, coolants and road contaminants. Made of Energy’s Hyper-Flex performance polyurethane and heavy duty hardware – for added durability.
