Namura Technologies NA-40011K Top End Repair Kit Standard Bore

The Namura Technologies NA-40011K is a complete top end repair kit designed to restore engine performance and reliability. This comprehensive kit includes everything needed for a professional top end rebuild: piston, rings, wrist pin, clips, top end bearing, and complete gasket kit.

Advanced Piston Technology:

• MOS2 Coated Skirts: Features a rolled-on Teflon/Molybdenum coating that bonds 10 times stronger than spray-on alternatives, providing increased heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Heads: Precision-machined dome surface reflects combustion heat and reduces carbon buildup, potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Hard anodizing increases heat resistance and durability, making the piston 75% stronger than non-anodized designs
• Hypereutectic Casting: High silicon content construction provides reduced thermal expansion rates, superior wear resistance, and improved ability to withstand high cylinder temperatures

This standard bore kit delivers OEM-quality components with performance-enhancing features, making it an excellent choice for engine rebuilds on powersports vehicles, motorcycles, ATVs, and other small engines.
