Mahle MS piston rings are file-fit rings sized 3.858 in (98.00mm) with a 1.2mm, 1.2mm, 3.0mm ring set profile intended for precise, single-cylinder or engine re-ring work. These rings are supplied for engines requiring file-fit sizing and allow machinists to custom-fit groove clearances and end gaps during rebuilds. They provide the fundamental sealing components needed for restoring compression and controlling oil consumption in affected bores.
