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

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the immense forces generated during combustion. Proper main bearing function is critical for engine health and performance.

What does 'bimetal' construction mean for these bearings?

Bimetal bearings, like these from King Engine Bearings, typically have a steel backing for strength and an aluminum overlay. This combination offers good fatigue strength and excellent conformability to the crankshaft journal, helping to maintain oil film.

Does this bearing set include everything needed for installation?

This listing is for the crankshaft main bearing set only. It is recommended to consult your vehicle's service manual for any additional components or specialized tools required for installation, such as crankshaft seals or assembly lube.
