Mahle Rings Performance Gas Nitride Steel 4.105 x .043 .157 RW Plain Ring Set

Mahle is well-known for making reliable engine components, and these Performance Gas Nitride Steel Piston Rings are a solid option when you're rebuilding or refreshing your engine. These rings are designed to seal the combustion chamber effectively, which is crucial for getting the most power out of your engine and keeping oil from getting into the combustion chamber. The set is for a 4.105 inch bore with .043 inch top and second rings and a .157 inch oil ring.

The nitride steel construction on these rings helps them stand up to the heat and stress inside the cylinder. This updated surface treatment offers improved wear resistance compared to standard cast iron rings, meaning they'll hold up better over time. They are a plain ring set, meaning they don't have any special coatings beyond the nitride treatment, making them a straightforward choice for many engine builds.
