Mahle Rings Performance Gas Nitride Steel 4.070 x .043 .157 RW Plain Ring Set

Mahle is known for making solid engine components, and these performance gas piston rings are no exception. If you're rebuilding an engine and need reliable rings that can handle the demands of performance use, this set is a good choice. They are made from nitride steel, which is a strong material chosen for its ability to resist wear and maintain sealing under pressure.

These rings measure 4.070 inches in bore size, with a thickness of .043 inches for the top and second rings, and .157 inches for the oil ring. The nitride treatment on the steel surface helps them hold up better to heat and friction, which is important for keeping your engine running smoothly and efficiently, especially when you're pushing it a bit harder. They are designed to fit right and seal well against the cylinder wall.
