What is the PMaxBlack coating for?

The PMaxBlack coating is a specialized surface treatment designed to enhance the bearing's ability to handle higher loads. This helps protect the bearing and the crankshaft journal under demanding operating conditions.

What does the Radialock feature do?

Radialock is a design feature that helps ensure the bearing achieves the correct 'crush height' when installed. Proper crush height is essential for the bearing to seat correctly and maintain oil pressure within the engine.

Are these bearings suitable for high-performance or turbocharged engines?

Yes, these bearings are designed for Subaru EJ20, EJ22, and EJ25 engines, including turbocharged variants. The PMaxBlack coating and tri-metal construction are intended to provide the necessary durability for higher performance applications.
