What does '0.010 inch undersize' mean for these bearings?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.010 inches. This is a common practice when rebuilding an engine to correct for wear on the crankshaft journals.

What is the material construction of these bearings?

These Clevite main bearings utilize a tri-metal construction. This advanced material offers a good balance of strength, conformability to the crankshaft, and wear resistance.

Do I need to purchase anything else to install these bearings?

Yes, when rebuilding an engine with main bearings, you will also need main bearing cap bolts, engine assembly lube, and potentially new crankshaft seals. It's also critical to have the crankshaft professionally machined to the correct undersize specification.
