What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, ensuring smooth operation and preventing metal-on-metal contact.

Why is proper oil clearance important for main bearings?

Proper oil clearance allows a thin film of oil to form between the bearing and the crankshaft. This oil film is essential for lubrication, heat dissipation, and preventing direct contact, which can lead to rapid wear and engine damage.

Are these bearings sold as a set?

Yes, these are sold as a set of main bearings designed to replace all the main bearings in your Chrysler 5.7L or 6.1L Hemi engine.
