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
The Namura NA-40009-BH Hyperdrive Piston Kit is designed for powersports engine rebuilds and replacement applications requiring a dependable piston assembly. This kit is supplied as a complete piston kit, providing a convenient solution for replacing worn or damaged piston components while helping restore proper engine performance and reliability. Namura is recognized for producing replacement engine components engineered for practical service and long-term use.
The Hyperdrive piston kit is intended to support consistent engine operation when installed with compatible cylinder, ring, pin, and retaining components. Replacing the piston as part of a properly planned top-end rebuild can help address performance concerns associated with wear, loss of compression, or piston damage. Always inspect the cylinder, connecting rod, crankshaft, and related top-end components before installation to confirm that the complete engine assembly is suitable for reuse.
Before ordering or installing the Namura NA-40009-BH, verify the part number and application against the engine manufacturer’s service information.
