What does the STDX size mean for these bearings?

The STDX designation means these bearings are 0.001 inch undersize compared to standard main bearings. This is often used when the engine's main bearing journals have been machined undersize, or to achieve tighter oil clearances for performance builds.

What is the pmax Black material?

The pmax Black material is King Engine Bearings' racing line. It's a tri-metal construction designed for increased strength and durability, making it suitable for engines that experience higher loads and stresses.

Are these bearings suitable for a stock engine rebuild?

While these bearings are built for performance, they can be used in a stock engine rebuild if you're looking for a well-built component. However, their racing line design is optimized for engines that may see more demanding use.
