The Mahle OE plain ring set is a direct-replacement piston ring kit for GMC trucks equipped with the 262ci (4.3L) engine from 1992–1994. Mahle’s piston rings prioritize OE-driven improvements: reduced friction and ring mass, lower oil consumption, and extended service life. This plain ring set follows that technology, offering reliable sealing and long-term durability for routine rebuilds or restorations on the specified GMC V6 engines.
