Namura Technologies NA-10012-4K Top End Rebuild Kit with Piston Rings Gaskets

The Namura Technologies NA-10012-4K top end rebuild kit provides a complete solution for engine top end restoration, delivering OEM-quality performance at an exceptional value. This comprehensive kit includes everything needed for a professional rebuild: forged piston, piston rings, wrist pin, circlips, top end bearing, and complete gasket set.

Advanced Piston Technology:

• MOS2 Coated Skirts: Teflon/Molybdenum coating applied through a rolled-on process creates a bond 10 times stronger than spray-on alternatives, increasing heat transfer, reducing friction, and preventing cold seizures
• Machined Smooth Head: Precision-machined dome reflects combustion heat and minimizes carbon buildup while potentially improving horsepower and fuel economy by up to 6%
• Anodized Dome: Hard anodizing treatment increases heat resistance and structural integrity, making the piston 75% stronger than non-anodized designs
• Hypereutectic Construction: High-silicon casting process reduces thermal expansion rates and increases wear resistance for extended service life and reliable performance at elevated cylinder temperatures

Namura pistons are engineered to meet or exceed OEM specifications, making this kit ideal for powersports enthusiasts, mechanics, and riders seeking reliable engine restoration components. Each component is manufactured to precise tolerances ensuring proper fit and long-lasting durability.
