NPR 10-853-2 Piston Set with Rings 0.50mm Oversize

The NPR 10-853-2 is a precision-engineered piston set with rings designed for engine rebuilding and performance restoration. Manufactured by Nippon Piston Ring Co., Ltd. (NPR of America), this component represents decades of Japanese engineering excellence in internal combustion engine parts.

Key Features:

• Premium aluminum alloy piston construction for durability and heat dissipation
• 0.50mm oversize specification for cylinder bore restoration
• Includes complete piston ring set engineered to NPR specifications
• Molybdenum-coated skirts for reduced friction and improved wear resistance
• Precision-machined to strict tolerances following JIS (Japanese Industrial Standard) B8032-6-1998
• Complete set includes pistons, wrist pins, and ring sets

NPR pistons feature advanced tribological engineering to provide optimal sealing, reduce oil consumption, and maximize engine performance. The piston rings are designed with proper tension and material composition to ensure complete contact with cylinder walls while maintaining the correct lubricant film thickness.
