NPR 10-920-0 Piston and Ring Kit for GM Engines 96.00mm Bore

The NPR 10-920-0 is a complete piston and ring kit designed for GM engines with a 96.00mm (3.780") bore diameter. This comprehensive kit includes all the pistons and rings needed for a complete engine rebuild, manufactured by Nippon Piston Ring Co., a trusted name in precision engine components since 1973.

Key Features:

• Complete kit contains all pistons and rings for full engine application
• Precision-engineered for 96.00mm (3.780") bore diameter GM engines
• MS (Molybdenum Surface) coating for enhanced durability and wear resistance
• Recommended clearance: 0.025mm (0.0010") measured from the bottom of the piston
• Premium aluminum alloy pistons with advanced surface treatments
• High-quality piston rings manufactured to JIS (Japanese Industrial Standard) B8032-6-1998
• Includes compression rings and oil control rings for complete sealing

NPR pistons and rings are designed to seal combustion gases, control lubricating oil, dissipate heat, and prevent wear under severe operating conditions. The rings feature chrome plating and advanced surface treatments including nitriding for superior wear resistance and durability. These components are engineered to reduce oil consumption, minimize blow-by, and deliver reliable performance in modern high-compression engines.

This kit follows NPR's naming convention where the "10-" prefix indicates a complete piston and ring kit, distinguishing it from individual components. Ideal for engine rebuilds and performance applications requiring precision-manufactured internal engine components.
