TOP END KITS
• 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
