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 handling the forces generated during combustion, ensuring proper lubrication and reducing friction.

What does the 'KV' designation mean for these Clevite bearings?

The KV designation refers to Clevite's specific design for oil flow management within the bearing. This updated design helps ensure consistent lubrication to the crankshaft journal, which is crucial for engine longevity and performance.

Are these bearings sold individually or as a set?

The product listing indicates these are individual main bearings. For a complete engine rebuild, you will need to ensure you have the correct quantity and part numbers for all necessary main bearings.
