Product Features
  • Hyperdryve pistons are manufactured from a hypereutectic aluminum alloy to perform under operating conditions that would normally require a forged piston.
  • Hyperdryve pistons are engineered to maintain their high tensile strength up to 700F (370C), while still being lighter than a standard cast piston.
  • Anodized piston head increases strength and heat dissapation.
  • MOST Namura pistons feature a machined head which helps reduce carbon build-up and reflect heat.
  • All components are manufactured to OE-specs.
  • Paper gaskets are composed of non-asbestos Nitrile Butadiene bonded cellulose fiber materials, which maintain their tensile strength and torque retention in operating conditions over 300F.
  • Seals and O-rings are made of either NBR, Fluoroviton, or Silicone. Each material is selected based on the following chacteristics: Temperature resistance, abrasion resistance, chemical resistance, and their Aniline Point. In certain applications a Teflon coating is also applied to prolong service life.
