Product Details

The Namura Technologies NX-20025K Top End Repair Kit provides a complete solution for rebuilding your engine's top end with premium components engineered for performance and durability. This comprehensive kit includes everything needed for a professional-quality rebuild: piston, rings, wrist pin, circlips, top end bearing, and complete gasket kit.

Advanced Piston Technology:

  • MOS2 Coated Skirts: Features a rolled-on Teflon/Molybdenum coating that bonds 10 times stronger than spray-on alternatives, increasing heat transfer, reducing friction, and eliminating cold seizures
  • Machined Smooth Heads: Precision-machined piston heads reflect combustion heat and reduce carbon buildup, delivering up to 6% gains in horsepower and fuel economy
  • Anodized Domes: Hard-anodized dome treatment increases heat resistance and makes pistons 75% stronger than non-anodized designs for extended service life
  • Hypereutectic Casting: High-silicon content construction provides superior wear resistance, reduced thermal expansion, and improved performance at elevated cylinder temperatures

Namura Technologies manufactures this top end kit to OEM specifications with premium materials and advanced coatings, making it an excellent choice for both stock rebuilds and performance applications. Each component is precision-engineered to ensure proper fitment and reliable operation.

Made it all so easy!

Easy enough to order. Not big on product description but manufacture gave me the part # I needed.

On drivers side, tube was contacting the body trim (2014 Toyota Access cab) after torqueing the bolts. Gap between body and tube was not uniform. Added small shim at center mount and approximately 1/4 inch shim in the front to achieve clearance and uniform gap. Longer bolt required. Right side installed perfect with no issues.

good price fast checkout
