What does the 010X sizing mean for these bearings?

The '010X' in the part number indicates that these main bearings are 0.010 inches undersize. This means the crankshaft journals they will be installed on should be machined down by 0.010 inches to match. This is a common practice in engine rebuilding to achieve proper clearances.

What is the benefit of the PMaxBlack coating?

The PMaxBlack coating is a proprietary material developed by King Engine Bearings. It's designed to enhance the bearing's ability to handle higher loads without deforming or failing, which is beneficial for performance engines or those under heavy stress.

Are these bearings suitable for a stock LS engine rebuild?

Yes, these bearings are well-suited for stock LS engine rebuilds, especially if the crankshaft journals have been machined to the 0.010 inch undersize. The tri-metal copper-based material and PMaxBlack coating offer improved durability and load capacity over standard bearings.
