About this part

Product Details

These Mahle Performance Steel Piston Rings feature a Napier hook design in the top ring, which helps improve oil control and reduce blow-by, especially under demanding conditions. The rings are constructed from durable steel and measure 4.505 inches in bore size with a .043 inch thickness for the top ring and .135 inch for the second ring. This bulk pack contains 48 sets, making it a solid option for engine builders or shops working on multiple projects.

The Napier hook design is a notable feature that helps the top ring "hook" oil and scrape it down the cylinder wall, ensuring proper lubrication while also creating a tighter seal. This construction contributes to improved engine performance and longevity. Mahle OE is a well-known name in engine components, and these rings are built to meet the needs of performance applications.
