HyperDryve Series piston
Kit Includes piston, rings, pin, clips, & top end gasket kit

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 Molybdenium 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
Namura gaskets use performance materials to increase durability and provide greater reliability
Includes all gaskets pictured to rebuild top end
Kit is for standard bore size - 97.00mm
