Mahle Rings Performance Steel Napier 2nd Ring 3.634in x 1.0MM .136in RW Plain Ring Set

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for proper compression and oil control. This Mahle OE Steel Napier 2nd Ring set is designed to help you achieve that reliable seal. The Napier hook on the second ring is a smart design feature that helps it rotate and scrape oil more effectively, which can mean less oil burning and better performance.

Mahle has been in the engine parts game for a long time, and these rings are well-built for the job. They're made from steel, which offers good durability and a strong seal against the cylinder wall. The specific dimensions here are 3.634 inches in diameter and 1.0mm thick for the ring itself, with a .136 inch groove width, ensuring they fit precisely into the corresponding piston grooves. This attention to detail means you can expect them to fit right and perform as expected during engine assembly.
