Overview of Namura Piston Assembly - 76.95mm Bore - NA-20000-4
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. 13-33264R
