The Namura Technologies NX10048CK Top End Repair Kit delivers everything needed to restore your powersports engine to peak operating condition in a single, convenient package. Engineered to OEM specifications, this kit eliminates the guesswork of sourcing individual components and is designed for a straightforward, reliable rebuild.

Kit Includes:

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

Key Piston Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts — Applied via a rolled-on process that creates a bond up to 10 times stronger than spray-on coatings, delivering increased heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Crown — Reflects combustion heat and minimizes carbon buildup on the piston top; testing has shown potential horsepower and fuel economy gains of up to 6%
• Anodized Dome — Enhances heat resistance and overall durability; anodized pistons offer up to 75% greater strength compared to non-anodized alternatives
• Hypereutectic Casting Process — Higher silicon content results in reduced thermal expansion rates, improved wear resistance, and the ability to withstand elevated cylinder temperatures

Namura rings are manufactured by Riken, the world's largest OEM ring producer, ensuring consistent ring gap and long-lasting sealing performance. The included gasket set covers head, base, and all other necessary gaskets, O-rings, and seals required to complete the rebuild — no additional parts needed.
