What does the 0.25mm undersize mean for these bearings?

The 0.25mm undersize specification means these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild. This ensures a proper fit and oil clearance on a reconditioned crankshaft.

What is the 'p-Max Black' racing line?

The p-Max Black racing line refers to King Engine Bearings' specialized overlay material. It's designed to offer enhanced durability and better load-carrying capabilities, making it suitable for performance engines that experience higher stress.

Are these bearings suitable for a stock engine rebuild?

While these are performance bearings, they can be used in a stock engine rebuild if the crankshaft journals have been machined to the 0.25mm undersize specification. For a stock rebuild without machining, you would typically need standard size bearings.
