What is the PMaxBlack overlay?

The PMaxBlack overlay is a proprietary material used by King Engine Bearings that is designed to provide superior load capacity. This helps the bearings withstand higher pressures and stresses in performance or heavy-duty applications.

What does 'Radialock' refer to?

Radialock is a feature of King Engine Bearings that helps maintain optimal crush height. This means the bearing is designed to seat properly and securely within the engine block during installation, ensuring consistent performance.

What is the difference between standard and undersize bearings?

Standard (STD) bearings are designed to fit crankshaft journals that are within the manufacturer's original specifications. Undersize bearings, like those marked -010 or -020, are used when the crankshaft journals have been machined down to correct for wear or damage.
