What is the pMax black coating?

The pMax black coating is a racing-focused material developed by King Engine Bearings. It's designed to provide enhanced durability and reduce friction, especially under high load conditions common in performance engines.

What does the +0.25mm sizing mean?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild. This ensures a precise fit and proper oil clearance for optimal engine performance.

Are these bearings suitable for a stock engine rebuild?

While these are XP Series racing bearings with a pMax black coating, they can be used in a performance-oriented stock rebuild. However, they are specifically designed to handle higher loads and reduced friction, making them a strong choice for engines that will be pushed.
