PISTON 94-00 POLARIS 300 75.50, NAMURA NA-50003-4 KIT ATV
Namura Piston Assembly. 75.50mm Bore. NA-50003-4. High-performance Namura pistons engineered in the USA, manufactured in Taiwan. High-silicon content Hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life and reduced scuffing. Machined, smooth piston crowns for reduced carbon buildup, increased horsepower and fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts reduce friction and heat for added power and longevity. Namura rings match the OEM design. Fractional oversize pistons available for some applications to extend cylinder life by renewing original clearance. Weight: 436g.
