Description

Namura's Top End kit is ideal for replacing worn parts and making some upgrades. Machined Smooth heads, available for certain models, can increase horsepower and fuel economy while reducing carbon buildup.

  • Top End kit includes: piston, rings, wrist pin, clips, top end bearing, and gasket kit
  • MOS2 (Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures
  • Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%
  • Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons
  • Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures
  • Piston Size: 66.36mm
  • Images are for reference purposes only
