What is the STDX size designation?

The STDX size indicates that these main bearings are 0.001 inch undersize. This is typically used when the crankshaft journals have been machined down to a specific undersize during a rebuild.

What makes the P-Max Black racing line different?

The P-Max Black racing line features King's most advanced overlay structure, designed to handle the extreme pressures and temperatures of racing. This design aims to reduce friction and improve oil flow for better engine protection.

Are these bearings suitable for a stock engine?

While these are high-performance racing bearings, they can be used in a well-built stock engine if specific clearances are desired. However, they are primarily intended for engines that experience higher loads and RPMs.
