Namura Technologies NX-40005-6R Piston Ring - Set 41.50mm

The Namura Technologies NX-40005-6R is a premium piston ring set designed for 41.50mm bore applications. This high-performance ring set is engineered to deliver superior sealing, durability, and performance in demanding powersports and small engine applications.

Advanced Coating Technology:

• MOS2 (Teflon/Molybdenum) Coated Skirts: Features a rolled-on application process that creates a bond 10 times stronger than spray-on coatings, providing increased heat transfer, reduced friction, and protection against cold seizures
• Machined Smooth Heads: Engineered to reflect combustion heat and reduce carbon buildup on the piston crown, potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Enhanced heat resistance and durability with anodization that makes pistons 75% stronger than non-anodized alternatives

Premium Construction:

• Hypereutectic Casting Process: Higher silicon content provides reduced thermal expansion rates, superior wear resistance, and the ability to withstand elevated cylinder temperatures
• Precision-manufactured to OEM specifications for reliable fitment and performance

Complete Top End Kit Includes: Piston, rings, wrist pin, circlips, top end bearing, and complete gasket kit—everything needed for a professional top end rebuild.

Namura Technologies is known for producing high-quality replacement pistons and ring sets that meet or exceed OEM standards, making this an excellent choice for engine rebuilds and performance applications.
