What does the '+.003in housing bore' mean for these bearings?

This means the inside diameter of the bearing housing is 0.003 inches larger than a standard bearing. This size is often used when the connecting rod housing has been machined to a larger size, or to achieve specific oil clearance targets during an engine rebuild.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. Typically, a set includes enough bearings for all the connecting rods in the engine.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. They allow the connecting rod to rotate smoothly around the crankshaft while maintaining a thin film of oil for lubrication and to control the precise clearance needed for proper engine operation.
