Clevite Ford Pass & Trk 240 250 300 6 Cyl 1966-93 Main Bearing Set

This is a Clevite Main Bearing Set, part number MS979A. What you get in this box are the main bearings needed to support the crankshaft in your Ford 240, 250, or 300 cubic inch inline-six engine. These bearings are crucial for keeping the crankshaft spinning smoothly and centered within the engine block, reducing friction and wear.

When you're rebuilding an engine, especially one from the 1966 to 1993 model years, using well-built bearings like these from Clevite is a smart move. They are designed to handle the pressures and temperatures inside the engine, helping to ensure a long life for your rebuilt motor. Proper installation is key here; make sure your crankshaft journals are clean and within spec, and always use a quality assembly lube to protect the bearings during initial startup.

This set fits a wide range of Ford trucks and vans from that era, including popular models like the F-150, E-150 Econoline, and Bronco. It's a solid option for anyone undertaking a major engine overhaul or repair.
