What is PMaxBlack technology?

PMaxBlack is a specialized overlay applied to the bearing surface. It's designed to increase the bearing's ability to withstand higher loads, which is beneficial for performance engines.

What does 'STD' size mean for these bearings?

STD stands for standard size. These bearings are meant for a crankshaft that is at its original factory specification and has not been machined undersize during a rebuild.

What is the benefit of the Radialock design?

The Radialock design helps the bearing achieve the correct 'crush height.' This is important because it ensures the bearing seats properly in the block and maintains the correct oil clearance for smooth operation.
