Product Details

This Clevite main bearing set features a 0.020 inch undersize, meaning it's designed to be used when the crankshaft journals have been machined down by 0.020 inches during an engine rebuild. These bearings are crucial for supporting the crankshaft and allowing it to spin freely within the engine block. They are built with a multi-layer construction, combining steel backings for strength with specialized bearing materials that handle the high pressures and temperatures found in performance engines.

When you're rebuilding a classic Chevrolet engine from the mid-50s to late-60s, like those found in a 1958 Chevrolet Impala or a 1965 Chevrolet Chevelle, using well-made bearings is essential for longevity and performance. Clevite has a long history of producing reliable engine components, and this set is no exception. The precise manufacturing ensures a proper fit and consistent oil clearance, which is vital for proper lubrication and preventing premature wear.

This set is designed to fit a wide variety of Chevrolet vehicles from 1955 through 1967, covering popular models like the Chevrolet Corvette, Chevrolet C10 Pickup, and Chevrolet Camaro. Ensure your crankshaft journals have been measured and machined to the correct undersize before installation, and always refer to your vehicle's service manual for specific installation procedures and torque specifications.
