MAHLE moly piston ring set for GMC passenger 350 5.7L engines, intended for 1990–1994 applications. MAHLE markets these rings as OE-driven technology that reduces friction and ring mass, helps minimize oil consumption, and supports longer service life. Offered as a direct replacement ring set, they aim to restore sealing efficiency and maintain engine oil control in older small-block V8 rebuilds.
