Namura Technologies NX70036K Top End Repair Kit - Standard Bore Piston Kit with Gaskets

The Namura Technologies NX70036K Top End Repair Kit includes everything needed to perform a complete top-end engine rebuild in one convenient package. The kit comes with a piston, rings, wrist pin, circlips, top-end needle bearing, and a full gasket kit — all matched to your specific application for a straightforward, no-guesswork rebuild.

Namura's pistons are engineered with several advanced features that set them apart from standard replacement parts:

• MOS2 (Teflon/Molybdenum) Coated Skirts: Applied via a roll-on process that creates a bond 10 times stronger than spray-on coatings. This coating improves heat transfer, reduces friction, and helps prevent cold seizures during startup.
• Machined Smooth Head: Reflects combustion heat away from the piston crown and reduces carbon buildup. This surface finish has shown potential gains of up to 6% in horsepower and fuel economy in testing.
• Anodized Dome: Increases heat resistance and durability — pistons with anodized domes are up to 75% stronger than non-anodized alternatives.
• Hypereutectic Casting Process: Delivers higher silicon content for reduced thermal expansion rates and improved wear resistance, allowing the piston to withstand higher cylinder operating temperatures.

The included gasket kit is manufactured to OE specifications, ensuring proper fitment without trimming or modification. Namura's Top End Repair Kits deliver premium piston technology at a fraction of the cost of cylinder replacement, making them a smart choice for powersports engine rebuilds.
