1400HD features

  • Utilises a 2618 alloy, the strongest available on the market today, with the best strength at high temperatures, coupled with low silicon content, for low porosity.
  • Heavy Radii, creating a large smooth radii from the skirts and pin boss into the crown, preventing flex and cracks.
  • Includes .225" wall Tool Steel Wrist Pins and heavy duty rings
  • Valve pocket design that allows maximum flow around valves - allows oversized valves and high lift cams to be utilized.
  • Piston crown shape designed to promote maximum intake charge efficiency through scavenging mixture "cross flow" during intake and exhaust valve overlap. More fuel and air equals more horsepower!
  • Pistons designed to optimize squish or quench during compression combustion cycle event, resulting in resistance to detonation and pre-ignition.
  • Complex piston skirt profiles that reduce power robbing friction, yet promote stability in bore for optimum ring seal.
