  • Moose Racing pistons feature X-style forgings and fully boxed-style (race pistons) forgings for ultimate strength, minimizing friction, durability, power, and weight reduction
  • The Pro Race Piston increases the durability by reducing the stresses in the pin bore area
  • The Pro Race Piston allows the pin to flex while removing stress from the area
  • Full radius dome designs maximize quench while eliminating hot spots that promote detonation
  • Internal bracing maximizes durability while decreasing friction in the pin assembly
  • Fully-boxed style (race pistons) forgings come standard with skirt coating which reduces friction, which in turn reduces heat (these are called out in the application chart)
  • Our race piston kits include a DLC pin; this technology has been proven and used because of its high resistance to abrasive wear, which extends the service life and reliability under extreme conditions
  • Each Moose Racing piston kit includes a high performance piston, wrist pin, rings, circlips and a top end gasket kit
  • Made in the U.S.A.
  • Be sure to use race fuel with some applications
