Namura Top End Repair Kit Complete top-end rebuild in one kit. The Namura Top End Repair Kit includes piston, rings, wrist pin, clips, top end bearing, and a full gasket kit — everything needed to restore performance and reliability. Key Features MOS2 (Teflon/Molybdenum) Coated Skirts: Rolled-on coating bonds 10× stronger than spray applications for improved heat transfer, reduced friction, and resistance to cold seizure. Machined Smooth Heads: Reflect combustion heat and minimize carbon buildup, protecting the piston crown. Can increase horsepower and fuel economy by up to 6% in some tests. Anodized Domes: Enhanced heat resistance and durability — anodized pistons are up to 75% stronger than non-anodized equivalents. Hypereutectic Casting: Higher silicon content delivers reduced thermal expansion, greater wear resistance, and improved tolerance to high cylinder temperatures. Benefits Optimize engine life and efficiency with precision components engineered for performance and long-term durability. Ideal for OEM replacement or high-mileage restorations, this kit simplifies installation while delivering measurable gains in wear resistance and combustion stability.
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
