Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 4.025in x 1.5MM .151in RW Moly Ring Set

Mahle OE is a well-known name in the engine parts world, often trusted for their reliable components. This particular set of top piston rings, the HV385, is crafted from plasma moly steel, a material chosen for its durability and performance characteristics. These rings are designed to fit a 4.025-inch bore and feature a 1.5mm thickness with a .151-inch groove width, making them a solid option for engine builds where improved sealing and performance are key.

The plasma moly coating on these rings helps reduce friction and wear, which can lead to a longer lifespan for both the rings and the cylinder walls. This is especially important in performance applications where engines are subjected to higher stresses. When you're rebuilding an engine and need dependable piston rings that offer improved sealing and wear resistance, this Mahle OE set is a strong contender.
