    Description

    Namura Forged pistons offer dyno-proven gains in performance and durability over industry-standard 4032 forged pistons. Namura's exclusive forged alloy offers lower expansion rates, allowing for tighter build tolerances and superior tensile and yield strength at operating temperatures.

    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
    • Kit comes with one individually wrapped piston
    • A set of OEM quality rings (packed in their own box)
    • An OEM quality wrist pin, and cir-clips.

    Additional Information

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