Namura NX-10070-4 Piston Kit 1.00 oversize 48.00mm. High-performance Namura pistons engineered in the USA and manufactured in Taiwan. Hypereutectic cast aluminum material with high-silicon content for less heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. Machined, smooth piston crowns reduce carbon buildup, increase horsepower and fuel economy. Hard anodized crowns are 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures. 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. Weight 140g.
