What is PMaxBlack technology?

PMaxBlack is a technology developed by King Engine Bearings that enhances the load capacity of the bearings. This makes them suitable for engines that experience higher stresses.

What does 'optimal crush height' mean?

Radialock technology helps achieve optimal crush height. This refers to the amount the bearing deforms when installed, ensuring a snug and secure fit within the connecting rod housing.

What is the material of these bearings?

These bearings are made from a tri-metal copper-based material. This construction is chosen for its durability and performance characteristics in engine applications.
