What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This type of bearing material is well-suited for the demands of engine operation, providing good wear resistance and oil compatibility.

Are these bearings a direct replacement for all Mitsubishi 4G52 engines?

This specific set, MB577AM0.75, is an optional replacement for the MB5441AM part number, which has a 3/4 groove design. Always confirm your specific engine's requirements and the condition of the crankshaft journals before ordering.
