What does the 0.020 inch undersize specification mean?

The 0.020 inch undersize specification indicates that these bearings are intended for use with a crankshaft that has been machined down by 0.020 inches. This is typically done during an engine rebuild to correct wear on the crankshaft journals or to achieve specific bearing clearances.

What type of material are these bearings made from?

These bearings are made from a bi-metal aluminum material and feature an Alecular high-performance composite. They are also designed to be lead-free for environmentally safe operation.

Are these bearings suitable for stock replacement or performance builds?
