Mahle Rings Performance Steel Napier 2nd Ring 3.3169in x 1.2MM .135in RW Plain Ring Set

This is a set of Mahle OE Piston Rings, specifically the 3021324 model. These rings are designed for engine rebuilds where performance and durability are key. The second ring features a Napier hook design, which helps improve oil control and reduce blow-by, especially under demanding conditions. This particular set uses a 1.2mm thickness for the second ring and a .135 inch thickness for the oil ring, ensuring a good seal within the cylinder bore.

Constructed from durable steel, these rings are built to withstand the heat and pressure found in performance engines. The Napier design on the second ring is a well-known feature that helps the ring 'dig in' to the cylinder wall on the downstroke, scraping oil effectively. This contributes to better compression sealing and reduced oil consumption over time. Mahle OE is a trusted name in engine components, and this ring set reflects their commitment to well-built parts for engine work.
