NAMURA NX-20031-C C Series Piston Kit

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

Restore dependable engine performance with the NAMURA NX-20031-C C Series Piston Kit. Designed for powersports and small-engine repair applications, this replacement kit provides a practical solution when the original piston has experienced wear, damage, or performance loss. The C Series designation identifies the specific configuration, making it important to confirm the required application and piston specifications before ordering or installation.
Use the NAMURA NX-20031-C as part of a proper engine rebuild or top-end service. A correctly matched piston kit can help support consistent compression, efficient combustion, and reliable operation when installed with the appropriate cylinder, rings, pin, clips, and related components.
