What is the purpose of crankshaft main bearings?

Crankshaft main bearings support the crankshaft within the engine block. They reduce friction as the crankshaft spins and also handle the forward and backward thrust forces generated during engine operation.

What does 'flanged bearing thrust' mean?

Flanged bearings have a lip or flange on one side. This design is specifically intended to control the axial (forward and backward) movement of the crankshaft, preventing it from shifting too far in either direction.

Are these bearings sold individually or as a set?

This is a complete set of crankshaft main bearings designed to replace all the main bearings in your V6 engine during a rebuild.
