Mahle Rings Performance Gas Nitride Steel 4.095 x .043 .157 RW Plain Ring Set

These Mahle Performance Gas piston rings are made from nitride steel, a material chosen for its solid wear resistance. The rings measure 4.095 inches in bore size, with a thickness of .043 inches for the top and second rings, and .157 inches for the oil ring. This specific sizing and material choice is important for ensuring a good seal between the piston and cylinder wall, which is critical for engine performance and longevity.

The nitride treatment on the steel surface further enhances its hardness and resistance to scuffing, helping these rings stand up to the demands of a performance gas engine. When you're rebuilding an engine, getting the right piston rings is key to proper compression and oil control. Mahle has been a well-known name in engine components for a long time, and these rings reflect their focus on durable, functional parts for engine builds.
