Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 3.228in x 1.0MM .143in RW Moly Ring Set

Mahle OE is a well-known name in the engine parts world, often chosen for their reliable components. This set of top piston rings, specifically the HV385 model, is made from plasma moly steel. This material is chosen for its ability to stand up to wear, making these rings a solid option for rebuilding or refreshing an engine where durability is a key concern.

The rings measure 3.228 inches in diameter and are 1.0mm thick, with a 0.143-inch ring groove width. The plasma moly coating on these top rings helps to reduce friction and improve their lifespan, which is important for maintaining good compression and sealing within the cylinder. They are designed to fit right into the corresponding piston grooves, making installation straightforward for someone familiar with engine assembly.
