Product Details

Clevite is a well-known name in engine components, especially for their bearings. This MS483G20 main bearing set is designed for a range of domestic vehicles, making it a solid option if you're rebuilding the bottom end of your engine. These bearings are crucial for supporting the crankshaft and ensuring it spins smoothly within the engine block.

This particular set is built to handle the demands of older V8 engines. The construction focuses on providing a durable surface for the crankshaft to ride on, helping to reduce friction and wear. When you're putting an engine back together, especially one that's seen a lot of miles, using a well-made bearing set like this helps ensure the longevity and proper operation of your rebuild. They fit right into the main journals, providing the necessary clearance for oil to lubricate the critical surfaces.

This set fits a variety of vehicles, including models like the 1975 Oldsmobile 98, 1970-1979 Pontiac Firebird, and 1967-1977 Pontiac Catalina. Make sure to check the full fitment list to confirm compatibility with your specific application.
