Namura Technologies FX-40046 Forged Piston Kit - 96.95mm Bore 12.5:1 Compression

The Namura Technologies FX-40046 is a premium forged piston kit engineered for high-performance applications, featuring a standard bore of 96.95mm and a 12.5:1 compression ratio. This complete kit includes an individually wrapped forged piston, OEM-quality ring set, wrist pin, and circlips—everything needed for a professional rebuild.

Advanced Piston Features:

• MOS2 Coated Skirts: Rolled-on Teflon/Molybdenum coating creates a bond 10 times stronger than spray-on alternatives, improving heat transfer, reducing friction, and preventing cold seizures
• Machined Smooth Heads: Precision-machined dome reflects combustion heat and minimizes carbon buildup, potentially increasing horsepower and fuel economy by up to 6%
• Anodized Domes: Hard anodizing process increases heat resistance and delivers 75% greater strength compared to non-anodized pistons
• Hypereutectic Construction: High silicon content reduces thermal expansion rates and enhances wear resistance while withstanding higher cylinder temperatures

Complete Kit Includes:

• Forged piston with protective wrapping
• OEM-quality piston ring set
• Wrist pin and circlips
• Precision gaskets manufactured to OE specifications

Namura gaskets are designed for perfect fitment with no trimming required. All materials are selected for superior resistance to temperature extremes, oil, fuel, and coolant, and are tested to ASTM standards to meet or exceed OE performance specifications.
