What is the main function of crankshaft main bearings?

Crankshaft main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while handling the forces generated during combustion.

Do these bearings come with the necessary hardware for installation?

This product includes the main bearings themselves. You will need to refer to your vehicle's service manual for any additional hardware or specific installation requirements.

What is the significance of the '-30' in the part number 5M1051P-30?

The '-30' in the part number typically indicates that these bearings are 0.030 inches undersize. This is common when the crankshaft has been machined undersize during an engine rebuild to correct wear or damage.
