The Standard Ring Set (4 Ring) for Lister HR engines is a genuine Lister Petter service part designed to restore and maintain cylinder sealing, compression, and oil control. Supplied as a complete four-ring pack for one piston, it is manufactured from engine-grade metal alloys for durability under high temperature and load. Correct ring geometry and finish help reduce blow-by, stabilise oil consumption, and support reliable starting and steady running.
