Namura Technologies NX-40025K Top End Repair Kit with Piston, Rings & Gaskets

The Namura Technologies NX-40025K Top End Repair Kit provides everything needed for a complete top end rebuild. This comprehensive kit includes a high-performance piston, rings, wrist pin, circlips, top end bearing, and complete gasket set for a professional-quality repair.

Advanced Piston Technology:

• MOS2 Coated Skirts: Rolled-on Teflon/Molybdenum coating creates a bond 10 times stronger than spray-on alternatives, increasing 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 process increases heat resistance and durability, making pistons 75% stronger than non-anodized versions
• Hypereutectic Casting: Higher silicon content reduces thermal expansion rates and provides superior wear resistance at elevated cylinder temperatures

Namura pistons are engineered to meet or exceed OEM specifications, making this kit ideal for rebuilding two-stroke and four-stroke powersports engines. The complete gasket set ensures proper sealing for reliable performance.
