What does STDX sizing mean for these bearings?

STDX sizing means these main bearings are 0.001 inch undersize compared to standard specifications. This is important if your crankshaft has been machined to a specific undersize.

What is the pmax Black racing line?

The pmax Black racing line from King Engine Bearings features a tri-metal construction. This design is intended for performance applications where improved durability and load support are beneficial.

Are these bearings suitable for a daily driver?

While designed for racing, these bearings can be used in a daily driver if the engine is being rebuilt for performance or if you are machining the crankshaft to the appropriate undersize. They offer improved durability over standard bearings.
