What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined down by 1.0mm during an engine rebuild to ensure proper oil clearance and a snug fit.

What is the advantage of a bimetal aluminum base construction?

Bimetal construction, often using an aluminum alloy base, offers good wear resistance and heat dissipation properties. This combination helps the bearings withstand the high loads and temperatures within the engine while maintaining proper lubrication.

Is this bearing set a direct replacement for all Mitsubishi 4G52 engines?

This set is an optional replacement for the MB5441AM and is specifically sized at +1.0mm. Always verify your engine's specific requirements and crankshaft condition to ensure this size is appropriate for your rebuild.
