Product Details

This is a Clevite Main Bearing Set, part number MS1983A, designed for a range of Ford and Mercury vehicles from 1972 to 1992. These bearings are crucial for supporting the crankshaft within your engine block, allowing it to spin smoothly and efficiently. If you're rebuilding an engine or addressing issues like oil pressure loss or knocking noises, a fresh set of main bearings is a fundamental step to restoring proper engine function.

This set is built with Clevite's experience in engine components, aiming for reliable performance. The bearings are made to precise specifications to ensure they fit correctly and provide the necessary clearance for the crankshaft.
