What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilding to ensure proper clearance with worn or resurfaced crankshafts.

What are these bearings made of?

These main bearings are made with a bimetal construction, featuring an aluminum base. This material choice is common for engine bearings due to its ability to handle load and heat effectively.

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

This set is specifically sized at +0.25mm and is noted as an optional replacement for the MB 577AM set when a specific flange size is required. Always verify your engine's specifications and the condition of your crankshaft before ordering.
