What is the PMaxBlack coating and why is it important?

The PMaxBlack coating is a specialized surface treatment applied by King Engine Bearings. It's designed to increase the bearing's ability to withstand higher loads, which is beneficial for performance engines or vehicles used in demanding applications.

What does 'Standard Size' mean for these bearings?

Standard (STD) size bearings are meant to be installed on a crankshaft that has not been machined or ground undersize. If your crankshaft has been previously reconditioned or shows wear requiring machining, you would need an undersize bearing set.

What is Radialock technology?

Radialock is a feature designed by King Engine Bearings to help maintain the correct 'crush height' of the bearing. This ensures the bearing sits snugly in its housing, which is critical for proper oil clearance and preventing movement.

Product Details

King Engine Bearings has been specializing in engine bearings since 1960, focusing on supplying the highest quality parts available. This main bearing set, part number MB5280XPC, is designed for Ford 4.6L and 5.4L V8 SOHC engines, fitting a wide range of vehicles including the Ford F-150, Ford Mustang, and Lincoln Navigator. If you're rebuilding the bottom end of one of these popular Ford V8s, a solid set of main bearings is crucial for proper crankshaft support and oil pressure.

This particular set features King's PMaxBlack coating, which is engineered to handle superior load capacities, making it a strong choice for performance applications or heavy-duty use. The bearings are constructed from a tri-metal copper-based material, known for its excellent wear resistance and thermal conductivity. They also incorporate Radialock technology, which helps maintain optimal crush height during installation, ensuring a snug fit and consistent oil clearance. These bearings are standard size (STD), meaning they are intended for use with an unmachined crankshaft.
