What does +.5mm undersize mean for these rod bearings?

This means the bearings are manufactured to be 0.5 millimeters smaller in diameter than a standard bearing. This is necessary when the crankshaft journals have been machined down (ground) to a -.5mm size to remove wear or imperfections.

What is the pMaxKote coating?

pMaxKote is a dry lubricant coating applied by King Engine Bearings. It's designed to reduce friction and wear, particularly during the critical initial moments after an engine is started, helping to protect the bearing surface.

Are these bearings suitable for a stock rebuild?

These bearings are specifically designed for performance applications and engine rebuilds where the crankshaft journals have been ground undersize. If your crankshaft journals are still at standard size, you would need a standard size bearing.
