What is PMaxBlack material?

PMaxBlack is a proprietary material developed by King Engine Bearings. It's a tri-metal copper-based material designed to offer superior load capacity compared to standard bearings, making it suitable for performance applications.

What does 'Standard Size' mean for these bearings?

Standard size bearings, often abbreviated as STD, are designed to fit a crankshaft and block that have not been machined or modified from their original factory specifications.

Radialock is a feature of King Engine Bearings that helps to maintain the optimal crush height of the bearing during installation. This ensures the bearing seats correctly in the engine block for proper function.
