Namura Technologies NX-70051-C OEM Style Piston Kit C Series 0.02mm Oversize

The Namura Technologies NX-70051-C is an OEM-style piston kit in the C Series sizing, offering a +0.02mm oversize bore designed to extend the service life of expensive coated cylinders — including Nikasil, SCEM, Boron Composite, and Ceramic-lined bores. Built to exact OEM specifications, this piston is a direct replacement requiring no modifications or dimensional adjustments.

Key Features:

• MOS2 (Molybdenum/Teflon) Coated Skirts — Applied via a rolled-on process that bonds 10 times stronger than spray-on coatings, reducing friction, minimizing wear, and helping eliminate cold seizures
• Hard Anodized Dome — Anodized to HRB 105 hardness for superior heat resistance and durability; anodized pistons are significantly stronger than non-anodized alternatives
• Machined Smooth Piston Crown — Reflects combustion heat and reduces carbon buildup to protect the piston top
• Hypereutectic High-Silicon Aluminum Casting — Super-high silicone content provides reduced thermal expansion, additional wear resistance, and greater strength
• Riken OEM-Quality Rings — Rings are manufactured by Riken, the world's largest OEM ring manufacturer, delivering the same quality found in original equipment applications; rings also fit OEM pistons
• C Series Sizing (+0.02mm) — Ideal for cylinders requiring minimal material removal to restore proper clearances, helping preserve expensive cylinder coatings

Kit Includes:

• Individually wrapped piston
• OEM-quality ring set (packed separately)
• Wrist pin
• Circlips

The NX-70051-C delivers premium performance at an aftermarket price point, making top-end rebuilds more accessible without sacrificing quality or precision.
