King Engine Bearings GM Vortex / Gen III IV LS-Series Main Bearing Set

King Engine Bearings is known for making solid engine bearings, and this main bearing set for GM Vortex and Gen III/IV LS-series engines is no different. If you're rebuilding the bottom end of your LS engine, a good set of main bearings is crucial for ensuring proper oil clearance and smooth rotation of the crankshaft. This set is specifically designed for those engines, helping to maintain the integrity of your build.

This particular set is 0.020 inch undersize. This sizing is important when the crankshaft journals have been machined down during a rebuild to correct imperfections or to achieve a specific clearance. Using the correct undersize bearing ensures that you get the proper oil clearance, which is vital for the longevity and performance of your engine. King uses their high-performance overlay technology to create a well-built bearing that can handle the demands of these popular V8 engines.
