Clevite 42082CP Plasma-Moly Piston Ring Set Bore Standard - 4.065

The Clevite 42082CP is a premium plasma-moly piston ring set engineered for high-performance GM LS and LT V8 engines with a standard 4.065-inch bore diameter. Manufactured by MAHLE, a leading name in engine components, this ring set delivers superior sealing, durability, and reduced friction for engine rebuilds and performance applications.

Key Features:

• Plasma-moly face coating on compression rings for enhanced wear resistance and faster break-in
• Standard bore diameter of 4.065 inches
• Shallow groove design for modern piston specifications
• Carbon steel top compression ring with 0.0586-inch axial height
• Cast iron second compression ring with 0.0586-inch axial height
• Stainless steel oil ring assembly with 0.0984-inch axial height
• Premium-grade construction for reliable long-term performance

This piston ring set is designed for standard bore applications and provides excellent cylinder sealing while minimizing oil consumption. The plasma-moly coating reduces friction during the critical break-in period and ensures consistent ring-to-cylinder wall contact throughout the engine's operating life.
