Mahle Rings Performance Steel Napier 2nd Ring 3.4843in x 1.2MM .135in RW Plain Ring Set

This is a Mahle OE Piston Ring set, specifically featuring a steel Napier 2nd ring. These rings are crucial for sealing the combustion chamber, managing oil, and transferring heat from the piston to the cylinder wall. The Napier design in the second ring helps to scrape excess oil from the cylinder wall, which can improve oil control and reduce oil consumption, especially in performance applications.

Built with steel for durability, this set is designed to meet the demands of engine rebuilding. The precise dimensions, including a 3.4843-inch bore size, 1.2mm thickness for the second ring, and a 0.135-inch height, ensure a proper fit and function within the piston groove. Mahle OE is a well-known name in engine components, and this ring set is a solid option for anyone looking to restore or enhance their engine's performance.

Please note that this ring set is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for installation procedures and torque specifications.
