Federal Mogul Speed-Pro Main Bearing Set

The Federal-Mogul Speed-Pro Main Bearing Set is an engine crankshaft main bearing set. It is built for engine rebuilds and performance builds that need reliable crankshaft support. Speed-Pro is Federal-Mogul's performance and racing engine parts line. Main bearings (also called crankshaft bearings or engine bearing sets) carry the crankshaft and keep it rotating smoothly inside the engine block.

Key Features:

• Precision-manufactured bearing shells made to hold close tolerances and fit consistently
• Designed to support the crankshaft under high loads and sustained engine speeds
• Engineered to reduce friction and wear between the crankshaft journals and the block
• Built for street performance, towing, and general engine rebuild use
• Backed by Federal-Mogul's long-standing experience in engine bearing design

Use the right bearing size and clearance for your crankshaft and engine build. Proper oil clearance and clean installation are important for bearing life. Choose the variant that matches your application.
