Mahle Rings Perf Napier Steel 2nd Ring 4.160in x 1.0MM .136in RW Plain Ring Set (48 Qty Bulk Pack)

This bulk pack gives you 48 Mahle OE steel Napier second compression rings, each measuring 4.160 inches in bore diameter with a 1.0mm width and a .136 inch thickness. These rings are designed for performance applications, featuring a Napier hook design on the second ring. This design helps to improve oil control and prevent blow-by by scraping oil from the cylinder wall on the downstroke and creating a seal against the piston groove on the upstroke.

Mahle is a well-known name in engine components, and these rings are built to meet the demands of performance engines. The steel construction offers good durability for these critical sealing components. This set is intended for engine rebuilding projects where multiple engines or extensive component replacement is needed, offering a cost-effective solution for shops or builders working with many engines of the same bore size.

Please note that this product is not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for proper installation procedures and ring gap specifications.
