Mahle Rings Performance Plasma Moly Steel HV385 Top Ring 4.045in x 1.5MM .151in RW Moly Ring Set

This set includes the top piston rings you need for your engine rebuild. They are made from plasma moly steel, a strong material known for its wear resistance.

Mahle is a well-known name in engine components, and these rings are built to perform. The plasma moly coating on the top rings helps them stand up to the heat and friction inside the cylinder, which can lead to a longer lifespan for your engine. They are designed to fit right into the corresponding piston grooves, making installation straightforward for someone familiar with engine work.
