Namura Technologies NA-10007-4 OEM Style Piston Kit .040 Oversize

The Namura Technologies NA-10007-4 is a high-performance OEM-style piston kit designed for .040" oversize applications. Engineered with advanced materials and coatings, this piston kit delivers superior durability and performance for rebuilt engines.

Advanced Coating Technology:

• MOS2 (Teflon/Molybdenum) Coated Skirts: Utilizes a rolled-on application process that creates a bond 10 times stronger than traditional spray-on coatings, providing increased heat transfer, reduced friction, and protection against cold seizures
• Anodized Domes: Hard anodizing increases heat resistance and durability, making pistons 75% stronger than non-anodized alternatives

Performance-Enhancing Features:

• Machined Smooth Heads: Precisely machined surface reflects combustion heat and reduces carbon buildup, protecting the piston crown while potentially increasing horsepower and fuel economy by up to 6%
• Hypereutectic Casting Process: Higher silicon content provides reduced expansion rates, additional wear resistance, and superior ability to withstand elevated cylinder temperatures

This complete piston kit includes the piston, rings, pin, and circlips needed for installation. The .040" oversize designation makes it ideal for engines that have been bored to restore proper piston-to-cylinder wall clearance during rebuilds.
