What does 'STD' size mean for these main bearings?

STD stands for standard size. This means the bearings are intended for use with a crankshaft that has not been machined undersize. If your crankshaft has been ground undersize, you would need a different bearing size.

What is the advantage of the lead-free composite material?

The lead-free composite material is environmentally safe and offers good performance for low to medium-load engines. It helps provide a reliable bearing surface without using lead, which is often restricted in modern manufacturing.

Does this main bearing set come with all the necessary components for installation?

This listing is for the main bearing set only. It includes the main bearings themselves. It's recommended to consult the manufacturer's installation guide for any additional hardware or specialized tools that may be required for proper installation.
