MAHLE Performance 302-0261 is a second compression ring for 4.310in bore, 5/64in in axial height. It is built from grey iron.
Key Features
- Second ring duty is roughly 80% oil control and up to 20% compression control
- Grey iron works well in moderate performance service and is a common choice for second ring duty.
- The reverse-twist taper faced design uses an inside bevel to create torsional twist, which limits oil migration up behind the ring while the taper face scrapes the cylinder wall.
