What does the 0.030 size indicate for these bearings?

The '030' in the part number MB5013XP030 indicates that these main bearings are 0.030 inches undersize. This means they are intended for crankshafts that have been machined down by 0.030 inches during an engine rebuild.

What is the benefit of the PMaxBlack overlay?

The PMaxBlack overlay is a specialized coating King Engine Bearings uses to enhance the load-carrying capacity of the bearing. This is particularly beneficial for performance engines that experience higher stresses and loads than stock applications.

Does this bearing set come with all necessary hardware for installation?

This product is a main bearing set, which includes the main bearings themselves. It does not typically include other installation hardware like main cap bolts or engine assembly lube, which should be sourced separately.

About this part

Product Details

The tri-metal copper-based material in this King Engine Bearings main bearing set is a key component for handling the demands of performance LS engines. Specifically, these bearings are 0.030 inches undersize, which is important to note when rebuilding or refreshing your engine.

King specializes in engine bearings, and this set is designed for GM's popular LS-series engines, including the LS1, LS6, and LS3. The Radialock feature helps ensure optimal crush height during installation, which is critical for proper bearing seating and oil clearance. This attention to detail in design and material selection is what King focuses on to provide reliable engine components.

This main bearing set fits a wide range of GM vehicles equipped with LS engines, from performance cars like the Chevrolet Corvette and Camaro to trucks and SUVs like the Cadillac Escalade and Chevrolet Silverado. If you're rebuilding the bottom end of your LS engine, these bearings offer a well-built option with advanced features aimed at durability and performance.
