Federal Mogul Crankshaft Main Bearing Set Oversize

The Federal-Mogul crankshaft main bearing set in oversize sizes is made for engine rebuilds where the crankshaft journals have been ground undersize. Oversize and undersize bearings are often called "main bearings," "crank bearings" or "engine bearing sets." They restore proper oil clearance between the crankshaft and the engine block.

Key Features:

• Supports the crankshaft and lets it rotate smoothly under load
• Made for precision-machined crankshaft journals after regrinding
• Multi-layer construction helps resist wear, fatigue and heat
• Helps maintain correct oil film and clearance for engine durability
• Backed by Federal-Mogul's long history as an original equipment bearing supplier

These bearings suit engine rebuilds, remanufacturing and performance builds. Check the journal diameters and the bearing size for your engine before installing. Careful measurement and clean assembly help get the most life from a rebuilt engine.
