What does the PMaxBlack material offer?

PMaxBlack is a tri-metal copper-based material developed by King Engine Bearings. It is designed to provide superior load capacity, which is beneficial for critical engine components like main bearings.

What is the significance of the #5 position thrust bearing?

The #5 main bearing is often designed to handle the axial thrust loads on the crankshaft. Having a bearing specifically designed for this thrust application helps manage these forces effectively, contributing to the engine's overall health.

Are these bearings a direct replacement for all Subaru EJ engines?

These bearings are specifically sized STD (standard) and designed for the thrust position in the #5 main bearing. While they fit a wide range of Subaru EJ20, EJ22, and EJ25 engines, it's important to verify the specific bearing size and position required for your engine build.
