Mahle Rings Plasma Moly Steel Top Compression Ring 4.125in x 1/16in .190in RW Moly Ring Set

This top compression ring from Mahle is made from plasma moly steel, a strong material chosen for its durability in high-heat environments. It's designed for a 4.125-inch bore and features a 1/16-inch thickness with a .190-inch ring depth, ensuring a solid seal within the cylinder. This specific design helps maintain consistent compression and reduces blow-by, which is crucial for engine performance and longevity.

Mahle has built a reputation for well-made engine components, and this ring set is no exception. The plasma moly coating on the steel provides improved wear resistance, helping the ring stand up to the rigors of combustion. This means you can expect reliable performance and a longer service life from your engine rebuild.
