Clevite Main Bearing Set

This Clevite Main Bearing Set, part number MS540P20, features a 0.020 inch undersize. Main bearings are critical for supporting the crankshaft within the engine block, ensuring it spins smoothly and with minimal friction. When rebuilding or refreshing an engine, especially for older Dodge and Plymouth vehicles, using well-built bearings like these from Clevite is essential for proper oil clearance and long-term durability.

Clevite uses a tri-metal construction for these bearings, which is a popular choice for performance and heavy-duty applications because it offers a good balance of strength and conformability. This means the bearing can adapt to slight imperfections in the crankshaft journal while still providing a strong, wear-resistant surface. The 0.020 inch undersize is important to note; this set is intended for use with a crankshaft that has been machined down by 0.020 inches to correct for wear or damage.

This set is designed to fit a wide variety of Dodge and Plymouth vehicles from the mid-1950s through the early 1970s, including models like the Dodge Charger, Dodge D-Series trucks, and Plymouth Barracuda. Ensure your crankshaft has been properly machined to the 0.020 inch undersize before installation.
