HyperDryve Series piston
Kit Includes piston, rings, pin, clips top end gasket kit (you get exactly what is pictured)
The HyperDryve line of pistons is composed of a space-age hypereutectic aluminum alloy developed by NASA. Engineered to maintain its high tensile strength up to 700?? F(370??C), 50% higher than a conventional cast piston, this gives HyperDryve pistons the strength to perform under operating conditions normally reserved for forged pistons.
Piston skirts are Molybdenum Teflon coated to minimize resistance/wear and provide extended life. Also allows for smoother start-ups break-ins.
Piston dome is anodized for superior heat resistance and longer lifespan
gaskets use performance materials to increase durability and provide greater reliability
Includes all gaskets pictured to rebuild top end
