King Engine Bearings Pontiac 455 (Size .001) Main Bearing Set

This set includes the main bearings you need for your Pontiac 455 engine rebuild. Specifically, these are a .001 inch undersize set, which is important if you're machining your crankshaft to match.

King Engine Bearings is a well-known name in engine components, and these main bearings are built to handle the demands of a performance or rebuilt engine. They are designed to provide a solid oil film between the crankshaft and the block, which is crucial for reducing friction and wear. Using the correct bearing size is key for proper oil clearance, and this .001 undersize set is for applications where the crankshaft journals have been ground down by that amount.
