    Description

    Why replace your cylinder when you can replace the piston for a fraction of the cost and time? Namura piston kits come with the piston individually wrapped; a set of OEM quality rings packed in their own box, a wrist pin, and circlips.


    Additional Note

    Kit comes with one individually wrapped piston, one set of OEM quality piston rings, a wrist pin, and circlips.

    Features

    • MOS2 (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 horsepower 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
    • Comes with the piston individually wrapped
    • Contains OEM quality rings, a wrist pin, and circlips
    • One Piston contained per kit
