What does the 0.010 size mean for these bearings?

The '010' in the part number indicates that these bearings are 0.010 inches undersize. This means they are intended for crankshaft journals that have been machined down by 0.010 inches during an engine rebuild.

What is PMaxBlack and Radialock?

PMaxBlack is King's technology designed to improve load capacity, helping the bearings withstand higher pressures. Radialock is a feature that helps maintain the correct crush height, ensuring the bearings seat properly in the engine block.

Are these bearings suitable for a stock engine rebuild?

While these bearings feature performance-oriented technologies like PMaxBlack, their tri-metal construction and specialized features make them a strong choice for both stock and performance-oriented small block Chevy engine builds.
