What does the STDX size mean for these bearings?

The STDX designation indicates that these bearings are an undersize set. This is common when rebuilding an engine, as it allows for machining of the crankshaft journals to a specific tolerance. Always consult your engine's service manual for the correct bearing size needed for your application.

What is the benefit of the PMaxBlack overlay and Radialock technology?

The PMaxBlack overlay is designed to provide superior load capacity, making these bearings suitable for performance applications. Radialock technology helps ensure the bearings achieve optimal crush height, which is critical for proper seating and oil clearance within the engine.

Are these bearings sold individually or as a set?

This product is a set of four connecting rod bearings. This is typically enough for a 4-cylinder engine, which is common for the vehicles this bearing set fits.
