Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 4.035in x 1.5MM .151in RW Moly Ring Set

Mahle OE is a well-known name in the engine parts world, often recognized for their dependable OE-replacement components. This particular set is their Performance Plasma Moly Steel HV385 top ring, designed for a 4.035-inch bore with a 1.5mm ring width and a .151-inch groove depth. The plasma-moly coating on these steel rings is a tough surface treatment that helps reduce friction and wear, which is important for maintaining good compression and oil control over time.

These rings are a solid option if you're rebuilding an engine and need a durable, well-built set of top rings. The steel construction offers good strength, and the plasma-moly coating is a practical choice for engines that see regular use. It's worth noting that these rings are not CARB approved and cannot be shipped to California.
