Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 3.464in x 1.0MM .143in RW Moly Ring Set

Mahle OE piston rings are a solid choice when you're rebuilding an engine. This set features Plasma Moly Steel HV385 top rings, measuring 3.464 inches in diameter with a 1.0mm thickness and a .143 inch ring width. These rings are built to handle the demands of performance applications, offering improved sealing and durability.

The plasma-moly coating on these rings is a notable feature, known for its wear resistance and ability to reduce friction. This helps ensure a good seal between the piston and cylinder wall, which is crucial for maintaining compression and preventing oil from entering the combustion chamber. Mahle has a long history of supplying well-built engine components, and this ring set reflects that experience.
