Namura Technologies NX-40005-4R Piston Ring - Kit

The Namura Technologies NX-40005-4R is a premium piston ring kit designed for high-performance engine rebuilds. This comprehensive top-end kit includes everything needed for a complete piston assembly: piston, rings, wrist pin, clips, top-end bearing, and complete gasket kit.

Advanced Coating Technology:

• MOS2 (Teflon/Molybdenum) Coated Skirts: Features a rolled-on application process that creates a bond 10 times stronger than spray-on coatings, providing increased heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Heads: Precision-machined surface reflects combustion heat and reduces carbon buildup on the piston crown, potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Hard anodized finish increases heat resistance and durability, making the piston 75% stronger than non-anodized alternatives

Premium Construction:

• Hypereutectic Casting Process: Advanced manufacturing provides higher silicon content for reduced thermal expansion rates and superior wear resistance
• Enhanced ability to withstand higher cylinder temperatures for improved reliability and longevity
• Precision-engineered components ensure proper fit and optimal engine performance

Ideal for mechanics and enthusiasts performing top-end rebuilds on powersports engines, this Namura kit delivers OEM-quality performance with advanced materials and coatings designed for demanding applications.
