Mahle Rings Perf Steel Napier 2nd Ring 4.320in x .043 .135in RW Plain Ring Set (48 Qty Bulk Pack)

This bulk pack gives you 48 Mahle OE steel Napier 2nd rings, each measuring 4.320 inches in bore diameter, with a 0.043 inch width and 0.135 inch thickness. These rings are designed for performance applications, featuring a Napier hook design on the second ring. This design helps improve oil control and prevent blow-by, especially under demanding conditions. The steel construction offers good durability for engines that see regular use or are built for more spirited driving.

Mahle is a well-known name in engine components, and these rings are made to their OE specifications. The Napier hook on the second ring is a notable feature that helps the ring rotate slightly in its groove, which can improve its ability to scrape oil off the cylinder wall and maintain a good seal. This bulk pack is ideal for shops or builders who frequently work on engines requiring this specific ring size and configuration.
