What does the 0.75 size mean for these bearings?

The 0.75 size indicates that these main bearings are 0.075 inches undersize from the standard factory size. This is typically used when the engine's crankshaft journals have been machined down during a rebuild to ensure a fresh, round surface.

What is the construction of these main bearings?

These main bearings feature a bimetal construction. This design uses an aluminum base, which is chosen for its performance characteristics within the demanding environment of an engine.

Are these bearings a direct replacement for all VG20E/VG20DET engines?

This set is specifically sized at 0.75 undersize and is an optional replacement for MB 453AM (flange STD). It's important to verify your engine's specific needs and crankshaft journal condition before ordering to ensure this size is appropriate for your rebuild.
