What is the purpose of the PMaxBlack technology?

PMaxBlack is a technology developed by King Engine Bearings to enhance the load capacity of their bearings. This means they can withstand higher pressures and stresses within the engine.

What does 'Radialock for Optimal Crush Height' mean?

Radialock refers to a design feature that helps the bearing achieve the correct 'crush height' when installed. Proper crush height ensures the bearing seats firmly in the engine block, which is essential for maintaining consistent oil clearance.

Are these bearings sold individually or as a set?

The MB1328XP is listed as a flange-only bearing and is part of the larger MB5013XP set. You will need to ensure you have the complete set for a full engine build.
