Mahle Rings Performance Gas Nitride Steel 4.135 x .043 .157 RW Plain Ring Set

This set includes the piston rings you need for a performance engine build. They are made from nitride steel, a strong material chosen for its ability to withstand the heat and stress inside a combustion chamber. The rings are designed for a 4.135 inch bore and feature a .043 inch ring thickness with a .157 inch oil ring width.

Mahle OE is a well-known name in engine components, and these rings are built to perform. The nitride treatment on the steel surface adds extra hardness, which helps them seal against the cylinder wall effectively. This is important for maintaining compression and controlling oil consumption, especially in engines that see harder use.
