Mahle Rings Performance Grey Iron Napier 4.365in x 1/16in .170in RW Plain Ring Set

These Mahle OE piston rings are made from grey iron, a solid material for engine components. They feature a Napier hook design on the second ring, which helps to scrape oil from the cylinder wall more effectively than a standard ring. This updated design can lead to improved oil control and reduced oil consumption. The rings measure 4.365 inches in diameter, with a 1/16 inch top ring thickness and a 0.170 inch oil ring width.

When you're rebuilding an engine, the piston rings are a critical part of sealing the combustion chamber and managing oil. Mahle has been a well-known name in engine parts for a long time, and these rings are built to perform. The grey iron material offers good wear resistance, and the Napier hook design is a practical choice for engines where oil control is important.
