What is the purpose of the PMaxBlack coating?

The PMaxBlack coating on these bearings is designed to enhance their ability to withstand superior load capacities. This makes them a solid choice for engines that experience high stress or are built for performance applications.

What does Radialock technology do?

Radialock technology is incorporated into the bearing design to help achieve optimal crush height. This ensures the bearing sits securely and correctly within the engine block for proper function.

What other parts are typically needed when replacing main bearings?

When replacing main bearings, it's common practice to also replace the crankshaft thrust bearing if applicable, and to ensure you have new engine oil and oil filter. It's also recommended to follow the manufacturer's specific installation instructions for torque specifications and assembly procedures.
