MAHLE Performance supplies 301-0660 as a single top compression ring for 3.5039in bore, measuring 1.5mm across the side faces. It is built from SAE 9254 steel with a chrome-plated face.
Key Features
- Barrel face profile for fast break-in and continued cylinder wall contact as the piston rocks at TDC and BDC
- 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.
