What is the purpose of main bearings in an engine?

Main bearings sit between the crankshaft and the engine block. Their job is to support the crankshaft, allowing it to rotate smoothly while maintaining the correct oil clearance and alignment.

Does this bearing set come with all the necessary parts for installation?

This listing is for the main bearing set itself. You will typically need to reuse your original main bearing caps and may require new main cap bolts and assembly lube for proper installation. Always refer to your vehicle's service manual for complete installation procedures.

Are these bearings undersized or oversized?

This is a standard size main bearing set. If your crankshaft has been machined (ground), you will need to order an undersized bearing set that matches the specific journal size.
