Mahle Rings Plasma Moly Steel Top Compression Ring 4.145in x .0625in .190in RW Bulk Moly Ring Set

Mahle OE is a well-known name in the engine parts world, often trusted for their reliable components. This set of top compression rings is made from plasma moly steel, a strong material chosen for its durability in high-heat environments. They measure 4.145 inches in bore size, with a ring thickness of .0625 inches and a groove thickness of .190 inches. These rings are designed to help maintain proper cylinder sealing, which is crucial for engine performance and efficiency.

When you're rebuilding an engine, the piston rings are a critical part of ensuring good compression and oil control. The plasma moly coating on these rings helps reduce friction and wear against the cylinder wall, contributing to a longer service life for both the rings and the engine itself. This set is a bulk pack, meaning it's intended for applications where you might need rings for multiple cylinders or as a convenient stock-up option.
