Namura Technologies NX-70004K Top End Rebuild Kit with Piston, Rings & Gaskets

The Namura Technologies NX-70004K is a complete top end rebuild kit designed to restore your engine to peak performance. This comprehensive kit includes everything needed for a professional-quality top end rebuild: piston, rings, wrist pin, circlips, top end bearing, and complete gasket set.

Advanced Piston Features:

• MOS2 Coated Skirts: Teflon/Molybdenum coating applied through a rolled-on process creates a bond 10 times stronger than spray-on alternatives, improving heat transfer, reducing friction, and preventing cold seizures
• Machined Smooth Heads: Precision-machined crown reflects combustion heat and minimizes carbon buildup while potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Hard anodizing increases heat resistance and structural integrity, making the piston 75% stronger than non-anodized designs
• Hypereutectic Casting: High silicon content construction provides superior wear resistance, reduced thermal expansion, and enhanced ability to withstand extreme cylinder temperatures

Namura pistons are engineered to meet or exceed OEM specifications, making this kit an excellent choice for rebuilding dirt bikes, ATVs, and other powersports engines.
