Product Details
Mahle is known for making OE-quality engine parts, and these Performance Napier Steel 2nd Ring sets are no exception. If you're rebuilding an engine and need reliable piston rings, this set is a solid option. The Napier style on the second ring is designed to help scrape oil from the cylinder wall, which can improve oil control and reduce blow-by.
This particular set features a 4.040-inch bore size with a 1.0mm second ring width and a .136-inch oil ring width. The steel construction of the second ring offers good durability for performance applications. These rings are designed for a plain fit, meaning they install directly onto the piston without special modifications.
