Product Details

This Clevite main bearing set features a 0.030 inch undersize, meaning it's intended for crankshafts that have been machined down by that amount during an engine rebuild. These bearings are built with a tri-metal construction, combining a steel backing for strength, a bronze-nickel intermediate layer for durability, and a lead-tin-copper overlay for excellent conformability and reduced friction against the crankshaft. This combination helps ensure a long service life and efficient operation for your engine's rotating assembly.

When you're rebuilding an engine from a classic Dodge or Plymouth, getting the main bearings right is crucial for supporting the crankshaft and maintaining proper oil clearance. Clevite has been a well-known name in engine bearings for a long time, and this set is designed to meet the demands of these older, often robust, engines. They fit a wide variety of vehicles from the late 1950s through the early 1970s, including popular models like the Dodge Charger, Challenger, and various D-series trucks. Proper installation, including ensuring the crankshaft is within the specified tolerance for these 0.030 inch undersize bearings and maintaining clean oil passages, is key to their performance.
