This is a set of five crankshaft main bearings from King Engine Bearings, specifically sized at 0.010 inches undersize. These bearings are crucial for the proper functioning of GM Vortec and LS-Series Gen III/IV engines, supporting the crankshaft as it spins within the engine block. King has been specializing in bearings since 1960, focusing on supplying well-built components for engine builds.

These main bearings feature King's PMaxBlack overlay, which offers superior load capacity, making them a solid choice for engines that see regular use or are built for more demanding applications. They also incorporate Radialock technology, designed to maintain optimal crush height during installation, which helps ensure the bearing stays securely in place. The tri-metal copper-based material is known for its durability and performance in engine bearing applications.

This set is designed to fit a wide range of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and Chevrolet Tahoe. When rebuilding or refreshing your engine, using bearings that are precisely sized and built with advanced materials is key to a long-lasting and healthy powerplant.
