King Engine Bearings GM Vortec /LS-Series Gen III IV V (Size +0.020) Main Bearing Set

These main bearings from King Engine Bearings are built 0.020 inches larger than the factory size. This specific sizing is crucial when you're rebuilding an engine that has had its crankshaft ground down to correct for wear or damage. The larger bearing surface helps to restore the proper clearances between the crankshaft and the engine block, which is essential for oil pressure and overall engine health.

King Engine Bearings uses a multi-layer material technology, with a steel-backed structure for strength and a specialized overlay material that's designed to work with various oil types. This combination aims to provide durable performance and good wear resistance for your rebuilt engine. They are designed to fit right into GM Vortec and LS-Series Gen III, IV, and V engines, making them a solid option for many popular V8 applications.
