If you're rebuilding the bottom end of your GM V8 engine, especially those popular LS-series variants, a solid set of main bearings is crucial for long-term health. This main bearing set from King Engine Bearings is specifically made for GM 294, 325, 345, and 364 cubic inch engines, covering displacements like the 4.8L, 5.3L, 5.7L, and 6.0L found in many trucks, SUVs, and performance cars.

These bearings are constructed from a bi-metal aluminum material, which is a well-built choice for medium-load engines. They also feature a lead-free composite, making them an environmentally safe option. This particular set is sized 0.030 inches undersize, which is important to note if you're machining your crankshaft to match.

This set fits a wide range of GM vehicles, including popular models like the Chevrolet Silverado, Cadillac Escalade, and Chevrolet Corvette. Always ensure your specific engine code and displacement match the application before ordering.
