FULL DESCRIPTION

Namura Piston Assembly - 67.40mm Bore - NX-10026-4

This Namura Piston Assembly is designed for high performance and longevity. Engineered in the USA and manufactured in Taiwan, it features a 67.40mm bore and is 1.00mm over size.

Key Features:

  • Material: High-silicon content Hypereutectic cast aluminum for reduced heat expansion, tighter clearances, increased hardness, longer life, and reduced scuffing.
  • Piston Crown: Machined, smooth piston crowns reduce carbon buildup, increase horsepower, and improve fuel economy.
  • Hard Anodized Crowns: 75% stronger than non-anodized, providing minimal expansion and reducing the chance of cold seizures.
  • Coated Skirts: MOS2 (Teflon/Molybdenum) coated skirts minimize friction and heat for added power and longevity.
  • Ring Compatibility: Namura rings match OEM designs.
  • Oversize Options: Fractional oversize pistons are available for some applications to extend cylinder life by renewing original clearance.
  • Included Components: Piston assemblies include ring(s), wrist pin, and circlips.
