ACL Bearings 5M1432H-10 Race Series Main Bearing Set Undersize Ford - 010 351W

The ACL Bearings 5M1432H-10 is a high-performance Race Series main bearing set engineered for Ford 351 Windsor, 351 Modified, and 400 V8 engines with .010 inch undersize crankshaft journals. Part of ACL's H-Series lineup, these bearings are designed for demanding racing and performance applications where reliability under extreme conditions is critical.

Key Features:

• Multi-layered tri-metal copper alloy construction with F780 bearing material for superior strength and seizure resistance
• Precision manufactured to micron-level tolerances for consistent wall thickness and proper crush
• Extended oil grooves and optimized oil distribution for enhanced lubrication
• .010 inch undersize for crankshafts machined to accommodate bearing wear or performance builds
• Enhanced bearing eccentricity and enlarged chamfers for improved oil flow
• Increased crush height ensures reliable bearing retention and optimal heat transfer
• Superior heat conduction properties to manage thermal loads in high-RPM applications

ACL Race Series bearings have proven themselves in competition from NASCAR to NHRA drag racing, delivering the dependability required for engines that see sustained high-RPM operation. Each bearing is manufactured with precision measurement systems to ensure reliable fit and maintain consistent clearances throughout the bearing's service life.
