    Namura Piston Assembly - 55.95mm Bore
    • 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. 13-3380SR
