About this part

Product Details

This main bearing set from King Engine Bearings includes the components you need for your GM Vortex, Gen III, or Gen IV LS-series engine. These bearings are specifically sized at 0.010 inch undersize, which is important when rebuilding or reconditioning an engine with a crankshaft that has been machined to match this size.

King Engine Bearings is a well-known name in engine components, and this set is built to meet the demands of performance and daily driving alike. The 0.010 inch undersize specification means these are intended for use with a crankshaft that has been turned down by that amount to correct wear or achieve a specific clearance. Proper bearing clearance is crucial for oil flow and engine longevity, ensuring your LS engine runs smoothly and reliably.
