What does the +.026mm size mean for these bearings?

The +.026mm designation indicates that these bearings are undersized by 0.026 millimeters. This means they are intended for use on a crankshaft that has been machined down to this specific undersize dimension during an engine rebuild.

What is PMaxBlack technology?

PMaxBlack is a technology developed by King Engine Bearings that enhances the load capacity of the bearings. This helps them withstand higher pressures and stresses within the engine, contributing to improved durability.

Are these bearings suitable for a stock engine rebuild?

These bearings are a +.026mm undersize, which means they are intended for engines where the crankshaft has been machined to that specific size. If your crankshaft is still at standard size, you would need a standard size bearing set.
