Namura Technologies NA-50003-2K Polaris Top End Repair Kit .020 Oversize

The Namura Technologies NA-50003-2K Top End Repair Kit provides a complete solution for rebuilding Polaris engine top ends with .020" oversize bore specifications. Engineered with premium materials and advanced manufacturing processes, this kit delivers OEM-quality performance at an aftermarket value.

Advanced Piston Technology:

• MOS2 Coated Skirts: Features a rolled-on Teflon/Molybdenum coating that bonds 10 times stronger than spray-on alternatives, providing superior heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Heads: Precision-machined piston heads reflect combustion heat and minimize carbon buildup, potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Hard-anodized treatment increases heat resistance and structural integrity, making pistons 75% stronger than non-anodized alternatives
• Hypereutectic Construction: Advanced casting process with higher silicon content reduces thermal expansion rates, increases wear resistance, and withstands higher cylinder temperatures for extended engine life

This top end kit includes all necessary gaskets and components for a complete rebuild. The .020" oversize specification is designed for cylinders that have been bored to restore proper tolerances and compression. Ideal for performance rebuilds, engine restoration, or repair of worn Polaris powerplants.
