What is the main purpose of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. Their main job is to reduce friction and wear by providing a smooth, low-friction surface for the rotating crankshaft, allowing the connecting rod to pivot freely.

Do these bearings come with new bolts or hardware?

This set includes only the connecting rod bearings. Any necessary bolts or other hardware for installation would need to be sourced separately according to your engine's service manual.

What is the significance of the 'AL20' in the part number?

The 'AL20' designation typically indicates that these bearings are 0.020 inches undersize. This is important for engine rebuilding where the crankshaft journals may have been ground undersize to clean up imperfections.
