Mahle Rings Performance Plasma Moly Steel Top Ring 4.000 x 5/64 .146in RW Moly Ring Set

When you're rebuilding an engine and need reliable piston rings, Mahle's Performance Plasma Moly Steel Top Ring Set is a solid choice. These rings are designed to seal the combustion chamber effectively, ensuring your engine runs smoothly and efficiently. They are built to handle the demands of performance applications, helping to maintain compression and prevent blow-by.

The top ring in this set features a plasma moly coating over steel, which is known for its durability and reduced friction against the cylinder wall. This combination helps extend the life of both the rings and the cylinder bore. The specific dimensions of 4.000 inches bore with a 5/64 inch width and .146 inch thickness are critical for a proper seal in many performance engine builds. Mahle OE is a well-known name in engine components, and this ring set reflects their commitment to well-built parts.
