Namura Top End Engine Rebuild Kit

  • All Namura Pistons have Molybdenium/Teflon Coatings that Minimize Resistance and Wear to Provide Extended Life
  • Anodized Domes That Provide Superior Heat Resistance and Extended Life Span
  • Super-High Silicone Content for Additional Strength
  • Premium World Class Rings Produced by the Largest Japanese OEM Supplier in the World


  • MOS(Teflon/Molybdenum) Coated Skirts
    A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures

    Machined Smooth Heads
    Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horse power and fuel economy by up to 6%

    Anodized Domes
    Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons

    Hypereutectic Casting Process
    Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures
