Mahle Rings Performance Gas Nitride Steel 4.585 x .043 .171 RW Plain Ring Set

Mahle is known for making solid OE replacement parts, and this Performance Gas Nitride Ring Set is no different. If you're rebuilding an engine and need a reliable set of piston rings, these are a well-built option. They are made from steel and feature a nitride coating, which helps them stand up to the heat and friction inside the cylinder.

These rings have a bore size of 4.585 inches and measure .043 inches thick for the compression rings, with a .171 inch oil ring. The nitride treatment is a surface hardening process that improves wear resistance and helps the rings seal better against the cylinder wall, which is crucial for good compression and oil control. This set is designed for performance gas applications, meaning they can handle the demands of a performance engine build.
