What does STDX size mean for these main bearings?

The STDX designation indicates that these bearings are manufactured to a specific undersize measurement. This is often used when the crankshaft has been machined down to a smaller diameter to ensure proper oil clearance and a precise fit.

What is King's unique overlay technology?

King's unique overlay technology refers to their specialized bearing material composition. It combines a strong overlay with a hardened steel-backed structure, designed to resist wear and maintain performance under high stress and load conditions.

Are these bearings suitable for street applications?

While these bearings are exceptionally well-built for high-performance and racing, their primary design is for extreme load conditions found in Top Fuel engines. For standard street use, other King bearing series might be more appropriate, depending on your specific engine build.
