What does the STDX size mean for these bearings?

The STDX designation means these bearings are 0.001 inch undersize compared to standard size. This is often used during engine rebuilding or when crankshaft journals have been machined undersize.

What is the pmax black material?

The pmax black material is part of King's racing line of bearings. It's a tri-metal material designed for high-performance applications, offering improved durability and load capacity.

Are these bearings suitable for daily driving or only racing?

While these bearings feature racing-oriented materials like pmax black, they are designed as a direct replacement for the specified engine sizes. They can be used for daily driving, but their construction is optimized for higher performance demands.
