What does '0.020 inch undersize' mean for these bearings?

This means the bearing's inner diameter is 0.020 inches smaller than a standard size bearing. This is typically used when the crankshaft has been machined down (ground) by 0.020 inches during an engine rebuild to ensure the correct oil clearance.

What is tri-metal construction?

Tri-metal construction refers to a bearing layer made of three different metals. This design is common in high-performance and heavy-duty applications because it offers a good balance of strength, embeddability, and resistance to corrosion and fatigue.
