Mahle Rings Performance Gas Nitride Steel 4.085 x .043 .157 RW Plain Ring Set

Mahle OE Performance Gas Nitride Steel Piston Rings are a solid option for rebuilding your engine. These rings are designed for a 4.085 inch bore with a .043 inch top ring, .043 inch second ring, and a .157 inch oil ring. The nitride steel construction offers good durability for performance applications.

The nitride treatment on these rings helps them resist wear and provides a solid seal against the cylinder wall. This is important for maintaining compression and controlling oil consumption. They are a plain ring set, meaning they don't have special coatings beyond the nitride treatment, making them a straightforward replacement for many performance builds.

When rebuilding an engine, ensuring proper ring seal is critical for performance and longevity. These Mahle rings are a well-made component to help you achieve that goal. Please note that these rings are not CARB approved and cannot be shipped to California.
