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

If you're rebuilding the bottom end of your Ford inline-six, a solid set of main bearings is crucial. This Clevite MS979P main bearing set is designed for Ford 240, 250, and 300 cubic inch 6-cylinder engines from 1966 through 1993. These bearings are what support your crankshaft, keeping it spinning true and reducing friction within the engine block. A well-built main bearing set is key to a healthy, long-lasting engine rebuild.

Clevite is a well-known name in engine components, and this set is built to meet the demands of your engine. The bearings feature a multi-layer construction with a steel backing for strength, a copper-lead alloy overlay for good embeddability, and a thin, hard chromium plating for reduced friction and improved oil retention. This combination helps ensure consistent oil film between the bearing and the crankshaft journal, which is vital for preventing wear, especially under load. They are designed to fit right into the factory main bearing bores, making installation straightforward for a mechanic.

This set is suitable for a wide range of Ford trucks and vans, including popular models like the F-150, E-150 Econoline, and Bronco from various years within the specified range. Make sure to check the full fitment list to confirm compatibility with your specific vehicle. Always refer to your vehicle's service manual for proper installation procedures and torque specifications.
