What is the main function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining the correct oil clearance, which is vital for lubrication and preventing friction.

Why is bi-metal construction used for performance bearings?

Bi-metal bearings combine a strong steel backing with a softer overlay material. This construction provides a solid foundation while allowing the bearing surface to conform to the crankshaft, reducing wear and handling higher loads.

Does this bearing set include all the necessary components for installation?

This set includes the main bearings. It is recommended to consult the manufacturer's installation guide or a service manual for a complete list of parts and procedures required for engine rebuilding.
