What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining proper oil clearance and supporting the forces generated during combustion.

What makes the King XP series bearings different?

The XP series bearings feature King's advanced overlay structure, which includes a high-performance overlay and a strong steel backing. This construction is designed for improved durability and performance under various operating conditions.

Do these bearings come with installation hardware?

This set includes the main bearings only. You will need to reuse your existing main caps and ensure all fasteners are properly torqued according to the manufacturer's specifications during installation.
