NAMURA PISTON KIT 66.90mm BORE. High-performance Namura pistons are engineered in the USA and manufactured in Taiwan using high-silicon content Hypereutectic cast aluminum material for less heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing. Features 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. 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. Cross reference numbers: NX-30027-2.
