What is the GPC overlay on these bearings?

The GPC overlay is a three-layer material used by King Engine Bearings. It's designed to offer better wear resistance and embeddability, which helps protect the bearings from damage caused by small particles in the oil.

Why is the +0.26mm sizing important?

This sizing indicates the bearings are slightly larger than standard, intended for use when the crankshaft journals have been machined undersize during an engine rebuild. It helps to achieve the correct oil clearance, which is crucial for proper lubrication and oil pressure.

Are these bearings sold individually or as a set?

This is a main bearing set, meaning it includes all the necessary main bearings required to rebuild the bottom end of the specified BMW engines.
