PISTON 94-00 POLARIS 300 75.00, NAMURA NA-50003-2 KIT ATV

Namura Piston Assembly - 75.00mm Bore

This high-performance Namura piston assembly is engineered in the USA and manufactured in Taiwan. Designed for durability and enhanced performance, this piston features a 75.00mm bore and is constructed from high-silicon content Hypereutectic cast aluminum. This advanced material offers reduced heat expansion, tighter clearances, increased hardness, and longer life, while also minimizing scuffing.

The piston boasts machined, smooth piston crowns engineered to reduce carbon buildup, ultimately contributing to increased horsepower and improved fuel economy. For even greater strength and resilience, the hard anodized crowns are 75% stronger than non-anodized versions, providing minimal expansion and significantly reducing the risk of cold seizures when paired with the Teflon/Molybdenum coated skirts.

The MOS2 (Teflon/Molybdenum) coated skirts are designed to perform at the highest standards, effectively reducing friction and heat for enhanced power output and extended longevity. Namura rings are designed to match OEM specifications, ensuring seamless integration and optimal performance.
