This open-stock second compression ring from MAHLE Performance covers 3.5709in bore in a 1.5mm axial height. It is built from SAE 9254 steel.
Key Features
- Second ring duty is roughly 80% oil control and up to 20% compression control
- SAE 9254 high alloy steel provides the tensile strength, hardness and fatigue resistance needed at high cylinder pressure, and its strength allows a lighter cross section that conforms better to an imperfect bore.
- 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.
- Supplied as a bulk open-stock pack of 48 rings
