Namura piston kit 67.40mm bore. High-performance Namura pistons are engineered in the USA and 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 reduce carbon buildup, increasing 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 are available for some applications to extend cylinder life. Part No. 56-W823_100.NT. Cross reference number NX-30027-4.
