Namura NX-10070-2 piston kit, 0.50mm oversize, 47.50mm. High-performance Namura pistons engineered in the USA, manufactured in Taiwan. Made from 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 when combined with Teflon/Molybdenum coated skirts. MOS2 (Teflon/Molybdenum) coated skirts perform at the highest standards, reducing friction and heat for added power and longevity. Namura rings match the OEM design. Available in .0004 inch and .0008 inch fractional oversize pistons for some applications to extend cylinder life by renewing original clearance if slightly worn, avoiding expensive sleeve installation. Weight: 134g.
