NPR 10-809-2 Piston Ring Set Ford 90.20mm Bore

The NPR 10-809-2 is a precision-engineered piston ring set designed for Ford engines with a 90.20mm (3.551 inch) bore diameter. Manufactured by Nippon Piston Ring Co., Ltd., this ring set exemplifies Japanese quality and engineering excellence that NPR has been known for since 1973.

Key Features:

• Precision bore diameter: 90.20mm (3.551")
• Manufactured to Japanese Industrial Standard (JIS) B8032-6-1998 specifications
• Advanced surface treatments for reduced friction and enhanced durability
• Optimized ring tension for proper sealing and oil control
• Chrome-plated construction for wear resistance
• Designed to reduce oil consumption and improve compression sealing

NPR piston rings are engineered to provide the optimal amount of lubricant film at cylinder contact points while maintaining complete contact against the piston groove. This ensures improved engine performance, reduced oil consumption, and extended engine life. Each ring set includes compression rings and oil control rings specifically designed for Ford applications.
