Namura Technologies NA-50090 Piston Kit Standard Bore Compression - 93.00mm 10.6 1

The Namura Technologies NA-50090 piston kit is engineered for Polaris RZR 900 engines, featuring a standard bore size of 93.00mm and 10.6:1 compression ratio. This complete piston kit delivers OEM-quality performance with advanced coating technologies and precision manufacturing.

Key Features:

• MOS2 Coated Skirts: Teflon/Molybdenum coating applied through a rolled-on process creates a bond 10 times stronger than spray-on alternatives, increasing heat transfer, reducing friction, and preventing cold seizures
• Machined Smooth Heads: Precision-machined crown reflects combustion heat and minimizes carbon buildup while potentially improving horsepower and fuel economy by up to 6%
• Anodized Domes: Hard anodizing treatment increases heat resistance and provides 75% greater strength compared to non-anodized pistons
• Hypereutectic Construction: High-silicon casting process reduces thermal expansion rates, enhances wear resistance, and withstands higher cylinder temperatures
• Complete Kit: Includes piston, rings, pin, and circlips for direct installation

This piston kit is designed as a direct replacement for stock Polaris RZR 900 applications, maintaining the original 93.00mm bore diameter and 10.6:1 compression ratio for reliable performance and durability.
