Product Details
When you're rebuilding the top end of your engine, getting the piston rings seated correctly is critical for sealing and performance. This Mahle OE Steel Napier 2nd Ring set is designed to help achieve that seal. The Napier hook on the second ring helps it rotate and maintain contact with the cylinder wall, which is important for proper oil control and preventing blow-by.
This set features a plain steel construction for the second ring, measuring 4.275 inches in diameter with a thickness of .043 inches and a height of .135 inches. Mahle is a well-known name in engine components, and these rings are built to meet the demands of an engine rebuild. They are designed to fit right and perform reliably once installed.
