What is the purpose of the performance coating on these bearings?

The multi-layer coating on these King main bearings is designed to reduce friction and wear. This is especially beneficial in performance engines that experience higher loads and temperatures.

What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are intended for a crankshaft that is at its original factory specification or has been machined back to standard size, not undersize.

Are these bearings suitable for a daily driver engine rebuild?

While these are performance-coated bearings, they are a well-built option for any engine rebuild. For a daily driver, ensuring the crankshaft is properly measured and the bearings are installed to manufacturer specifications will provide reliable performance.

About this part

Product Details

If you're rebuilding the bottom end of your Ford 302 CID Coyote engine, a solid set of main bearings is crucial. This performance-coated main bearing set from King Engine Bearings is designed to handle the demands of a performance build. They are a standard size, meaning they're intended for a crankshaft that hasn't been machined undersize.

King uses a unique overlay material on these bearings, which is a multi-layer coating that helps reduce friction and wear, especially in high-performance applications. This coating is applied over a strong steel backing, providing a well-built component that can handle increased loads and heat. The standard size ensures a direct fit onto a factory-spec or freshly machined crankshaft.
