This Mahle plain ring set is sized for a 4.425 inch bore with a 1/16 inch edge width and is specified as a grey iron THG second ring. Supplied as a matched plain ring set, it replaces the second compression ring during engine rebuilds to restore sealing and control blow-by where this exact bore and edge width are required. Use when the listed dimensions and second-ring specification match the engine build.
