What does the 'P25MM' in the part number mean?

Why are main bearings important for an engine rebuild?

Main bearings support the crankshaft within the engine block. Proper main bearings ensure the crankshaft spins smoothly with the correct oil clearance, which is vital for engine longevity and performance.

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