MOS2 (Teflon/Molybdenum) Coated Skirts – Namura starts a rolled-on application process that provides a bond that is 10 times stronger than other sprays on coatings. By using coatings on the piston this helps include increased heat transfer, reduced friction and this will help increase longevity.

• Namura Top End kit includes Mos2 Coated piston, rings, wrist pin, clips, and gasket kit
• Namura machines smooth heads of the piston - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston.
• By using a smooth top piston tests have shown this feature can increase horsepower and fuel economy by up to 6%
• Anodized Domes works with the smooth top piston  - 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
