What is the main purpose of main bearings?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while handling the forces generated during combustion.

What does the 'XP Series' designation mean for these bearings?

The XP Series from King Engine Bearings indicates a performance-oriented design. These bearings feature advanced materials and technologies like PMaxBlack and Radialock to handle higher loads and maintain proper fitment.

What material are these main bearings made from?

These main bearings are constructed from a tri-metal copper-based material. This type of material is chosen for its strength and ability to withstand the high pressures and temperatures found in an engine's rotating assembly.
