What is the PMaxBlack overlay and why is it important?

PMaxBlack is a proprietary overlay developed by King Engine Bearings. It's designed to provide superior load capacity, which is beneficial for engines that experience higher stresses, such as performance-tuned Subarus.

What does 'optimal crush height' mean for a bearing?

Crush height refers to the amount the bearing's outer diameter is intentionally oversized. This ensures the bearing firmly seats into the housing bore, which is critical for heat transfer and preventing the bearing from spinning.

Does this bearing set include all main bearings for the engine?

This specific part number, MB5220XP, is for the #3 position main bearing only. If you are rebuilding your engine, you will likely need a full set of main bearings, which would include bearings for other positions as well.
