What does it mean that these bearings are 0.040 inch undersize?

This means the bearings are slightly smaller than standard size. They are intended for use when the crankshaft has been machined down (ground) by 0.040 inches during an engine rebuild. This ensures a proper fit and oil clearance.

What is the material of these ACL main bearings?

These bearings are constructed from a tri-metal material. This type of material is chosen for its strength and ability to withstand the high loads and temperatures found in an engine's rotating assembly.

Do I need to buy anything else to install these main bearings?

When rebuilding an engine, you'll typically need a full engine gasket set, assembly lube, and potentially new main bearing bolts. Always refer to the manufacturer's installation instructions for a complete list of required items and procedures.
