Description

The Mahle oil ring support rail is a piston oil ring spacer designed for use in engines with a 4.260 in.-4.275 in. bore. It features a 2mm thickness and is sold individually. This support rail helps keep the piston from rotating, which improves cylinder seal, minimizes friction, and ensures the ring receives adequate gas pressure at high RPM.
