Namura Technologies NX-70000K Top End Repair Kit with Piston, Rings & Gaskets

The Namura Technologies NX-70000K Top End Repair Kit provides everything needed for a complete top end engine rebuild in a single, convenient package. Engineered to OEM specifications and beyond, this kit delivers enhanced performance, durability, and reliability for powersports engines.

Kit Includes:

• Piston
• Piston rings
• Wrist pin
• Wrist pin clips
• Top end bearing
• Complete gasket set

Key Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts — Applied via a rolled-on process that bonds 10x stronger than spray-on coatings. This advanced coating improves heat transfer, reduces friction, and helps prevent cold seizures during initial startup.
• Machined Smooth Crown — The smooth-machined piston head reflects combustion heat away from the piston and reduces carbon buildup. Independent testing has shown this feature can improve horsepower and fuel economy by up to 6%.
• Anodized Dome — The anodizing process increases heat resistance and overall durability. Pistons with anodized domes are up to 75% stronger than non-anodized counterparts, extending service life under high-stress conditions.
• Hypereutectic Casting — Namura's hypereutectic casting process yields a higher silicon content than standard castings, resulting in lower thermal expansion rates, improved wear resistance, and the ability to tolerate higher cylinder temperatures.

The Namura NX-70000K is a cost-effective solution for restoring top end performance, offering premium piston technology and a complete gasket set in one kit — reducing downtime and eliminating the need to source components separately.
