• High-performance Namura pistons are 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
• 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 except as noted
• -B (.0004 in.) and -C (.0008 in.) fractional oversize pistons, available for some applications, extend the life of your expensive cylinder by renewing the original clearance if its slightly worn, avoiding an expensive sleeve installation
• Piston assemblies include ring(s), wrist pin and circlips

• For replacement rings order PART NO. 13-3346SR

NOTE: Does not have machine smooth dome
