What does the 0.75 size designation mean for these bearings?

The 0.75 in the part number MB458AM0.75 indicates that these bearings are 0.00075 inches undersize. This means they are designed to be used when the engine's crankshaft journals have been machined down by that amount during an engine rebuild.

What is the construction of these main bearings?

These bearings feature a bimetal construction, which means they have an aluminum base. This design is common for main bearings as it helps with heat dissipation and provides a durable, smooth surface for the crankshaft.

Are these bearings sold individually or as a set?

This is a main bearing set, meaning it includes all the necessary main bearings required for a complete engine rebuild of the specified 3.0L 6G72 V6 engine.
