What is PMaxBlack technology?

PMaxBlack is a surface enhancement developed by King Engine Bearings. It is designed to provide superior load capacity, helping the bearings withstand higher stresses and pressures within the engine.

What is the benefit of Radialock design?

The Radialock design helps to ensure optimal crush height for the bearings. This is important for proper seating and sealing within the engine block, contributing to reliable oil pressure and performance.
