What does the 0.25mm size indicate for these main bearings?

The 0.25mm designation means these bearings are 0.25mm undersize. This is typically used when the crankshaft journals have been machined down to a specific undersize during an engine rebuild to ensure proper oil clearance.

What is PMaxBlack and Radialock technology?

PMaxBlack is a material developed by King Engine Bearings for superior load capacity. Radialock is a feature designed to help achieve optimal crush height, which is important for a secure and proper fit within the engine block.

Are these bearings suitable for a stock rebuild or a performance build?

These are performance main bearings, featuring materials and technologies like PMaxBlack for enhanced load capacity. They are well-suited for performance-oriented engine builds but can also be used in a stock rebuild where improved durability is desired.
