Kit includes HyperDryve series 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.
Cast piston has super-high silicone content for additional strength
Piston skirts are Molybdenum Teflon coated to minimize resistance/wear and provide extended life
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
Kit is for standard bore size – 95.00mm
Size A piston is 94.95mm
