Mahle Rings Performance Steel Napier 2nd Ring 3.815in x 1.0MM .136in RW Plain Ring Set

This Mahle OE Piston Ring set features a 1.0MM thick Napier hook on the second ring, a design choice that helps manage oil more effectively. The Napier hook is a specific shape that scrapes oil off the cylinder wall and directs it back into the crankcase, which is crucial for preventing excessive oil consumption and maintaining proper lubrication. These rings are made from steel and are designed for a 3.815-inch bore size, with a .136-inch ring height.

When you're rebuilding an engine, especially if you're looking for reliable performance, using well-made components like these Mahle rings makes a difference. The steel construction offers good durability for the demanding environment inside a cylinder. This set is intended for applications where precise fit and function are important for the engine's overall health and longevity.
