The Namura Technologies NA20076K Top End Repair Kit provides everything needed for a complete top-end engine rebuild in one convenient package. Engineered to exact OEM specifications, this kit delivers a high-performance piston assembly at an affordable price point — a practical alternative to costly cylinder replacement.

Kit Includes:

• Piston
• Piston rings
• Wrist pin
• Wrist pin clips
• Top end bearing
• Complete top end gasket kit (head, base, and all required gaskets, O-rings, and seals)

Piston Technology & Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts — Applied via a rolled-on process that creates a bond 10 times stronger than spray-on coatings, delivering increased heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Piston Head — Reflects combustion heat away from the piston crown and reduces carbon buildup; testing has shown this design can improve horsepower and fuel economy by up to 6%
• Anodized Dome — Enhances heat resistance and overall durability; anodized pistons are up to 75% stronger than non-anodized alternatives
• Hypereutectic Casting Process — High silicon content reduces thermal expansion rates and adds wear resistance, allowing the piston to withstand elevated cylinder temperatures
• OEM-Quality Rings — Manufactured by Riken, the world's largest OEM ring manufacturer, ensuring a precise fit with no modifications required

The included gasket set features head, base, and all other necessary gaskets, O-rings, and valve guide seals required to complete the rebuild. All components are individually packaged for easy identification during installation.
