Product Details
Mahle OE is a well-known name in the engine parts world, often trusted for their reliable components. This particular set features steel Napier rings, a design that's popular for its ability to help control oil and maintain a good seal, especially in performance applications. You're getting a bulk pack of 48 rings, which is handy if you're working on multiple engines or a larger project.
The rings are made from steel and have a Napier hook on the second ring, which helps scrape oil off the cylinder wall more effectively than a standard ring. This can lead to improved oil control and a better seal between the piston and cylinder wall. The dimensions are 4.095 inches for bore size, with a thickness of .043 inches for the top ring and .135 inches for the second ring. This specific configuration is often chosen for builds where consistent performance and good sealing are important.
