Clevite Chevy V8 348-409 1958-65 Main Bearing Set

This listing gets you a set of Clevite main bearings, designed for Chevy V8 engines displacing 348 to 409 cubic inches from 1958 through 1965. These bearings are a crucial part of your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. If you're rebuilding the bottom end of a classic Chevy big block, getting the right bearings is key to a long-lasting, healthy engine.

Clevite is a well-known name in engine components, and this set is built to meet the demands of these powerful V8s. The 'H' in the part number often indicates a high-performance or heavy-duty design, meaning these bearings are well-made to handle the stresses of regular operation. They are designed as a direct replacement, meaning they fit right into the factory main caps without modification, simplifying your rebuild process. Proper installation is critical for bearing life, so be sure to follow the manufacturer's torque specifications and use clean assembly lube.

This set is compatible with a range of classic Chevrolet models, including the Impala, Bel Air, and Biscayne from the late 50s and early 60s. Ensuring your crankshaft has solid support is fundamental to preventing premature wear and maintaining oil pressure.
