Mahle Rings Plasma Moly Steel Top Compression Ring 4.160in x 1/16in .190in RW Moly Ring Set

If you're rebuilding an engine, getting the piston rings right is crucial for sealing the combustion chamber. These Mahle OE Plasma Moly Steel Top Compression Rings are designed for a 4.160-inch bore, featuring a 1/16-inch width and a .190-inch thickness. They are built with plasma-moly steel, a strong material known for its durability and resistance to wear, which helps ensure a good seal and proper compression over time.

Mahle has a long history of supplying well-built engine components, and these rings are no exception. The plasma-moly coating on the top compression ring is a key feature, helping to reduce friction and improve the ring's ability to seat against the cylinder wall. This updated design contributes to improved engine performance and longevity, especially in rebuilt engines where a precise seal is paramount. They fit right into the piston groove, making them a solid option for your engine build.
