Mahle Rings Perf Steel Napier 2nd Ring 3.5531in x 1.2MM .135in RW Plain Ring Set (48 Qty Bulk Pack)

Mahle OE is known for making parts that meet original equipment specifications, and this set of steel Napier 2nd rings is no different. These rings are designed for engine rebuilding projects where precise fit and function are critical. The Napier hook design on the second ring helps to scrape oil from the cylinder wall, which can improve oil control and reduce blow-by.

This is a bulk pack containing 48 rings, making it a solid option for shops or builders working on multiple engines or performing a high-volume rebuild. The steel construction offers good durability for performance applications. Each ring measures 3.5531 inches in diameter, with a 1.2mm thickness and a 0.135-inch ring groove width. This specific set includes the second ring, which plays a key role in sealing the combustion chamber and managing oil.
