Namura Technologies NX-40005K Top End Repair Kit with Piston and Gaskets

The Namura Technologies NX-40005K is a comprehensive top end repair kit designed to restore engine performance and reliability. This complete 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:

Namura pistons feature MOS2 (Teflon/Molybdenum) coated skirts applied through a rolled-on process that creates a bond 10 times stronger than spray-on coatings. This coating increases heat transfer, reduces friction, and helps eliminate cold seizures during startup.

The machined smooth piston heads reflect combustion heat and reduce carbon buildup, protecting the piston crown. Testing has shown this feature can increase horsepower and fuel economy by up to 6%. The anodized domes provide 75% greater strength compared to non-anodized pistons while significantly increasing heat resistance and durability.

Premium Construction:

• Hypereutectic casting process with higher silicon content for reduced thermal expansion
• Enhanced wear resistance for extended service life
• Superior ability to withstand high cylinder temperatures
• Precision-machined components for optimal fit and performance
• Complete gasket set ensures proper sealing

This kit provides professional-grade components for ATV, motorcycle, or powersports engine rebuilds, delivering OEM-quality performance at an excellent value.
