What does '0.025 inches undersize' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than standard size. They are intended for use when the crankshaft journals have been machined down by 0.025 inches to ensure the correct oil clearance.

What is the purpose of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. They create a low-friction surface that allows the rod to rotate smoothly around the crank journal, distributing oil to keep parts lubricated and prevent metal-on-metal contact.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, a set includes all the bearings needed for a specific engine configuration, such as a 6-cylinder.
