Mahle Rings Performance Gas Nitrid Steel Oil Ring Assembly 4.0945in x 3.0MM .127inRW Plain Ring Set

The nitrided steel construction of this Mahle oil ring assembly is a key detail, offering improved durability and resistance to wear compared to standard materials. This specific ring set measures 4.0945 inches in diameter with a 3.0mm oil ring width and a .127-inch recovery width, designed for performance gas applications. Proper sealing is crucial for engine health, and these rings are built to help maintain that seal under demanding conditions.

Mahle is a well-known name in engine components, and this oil ring set reflects their focus on providing reliable parts for engine rebuilds. The nitriding process hardens the surface of the steel, which can lead to a longer service life for the rings and the cylinder walls they interact with. This is a solid option if you're looking to ensure good oil control and compression in your engine build.
