Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 3.307in x 1.0MM .143in RW Moly Ring Set

These Mahle HV385 top piston rings are built with plasma moly steel, a tough material chosen for its ability to resist wear and maintain sealing under demanding conditions. The 1.0mm thickness and .143 inch width are standard dimensions for many performance applications, ensuring a good seal against the cylinder wall. This set is designed to help restore compression and reduce oil consumption in your engine.

The plasma moly coating on these rings is a key feature. It's a hard, durable surface treatment that helps the ring slide smoothly against the cylinder wall, reducing friction and wear over time. This means the rings can last longer and maintain their sealing performance, which is crucial for keeping your engine running smoothly and efficiently. They are a well-built option for rebuilding or refreshing an engine where reliable sealing is a priority.
