ACL Bearings 4B1276P-20 Performance Connecting Rod Bearing Set Oversize - 020

The ACL Bearings 4B1276P-20 is a high-performance connecting rod bearing set designed for engine rebuilds requiring .020 inch (0.50mm) oversize bearings. ACL Race Series bearings are engineered to meet the demanding requirements of performance and racing engines, offering superior durability and reliability under high-RPM conditions.

Key Features:

• Tri-metal copper-lead construction for exceptional strength and wear resistance
• High-strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backing on all rod bearings for enhanced support and retention
• Increased crush design for improved bearing retention in the housing
• Optimized oil groove design for superior lubrication and oil distribution
• Tight wall tolerances to help maintain consistent bearing clearances
• Enhanced heat transfer properties for improved thermal management
• .020 inch oversize for machined crankshaft journals

ACL bearings feature advanced metallurgy and precision engineering that delivers the endurance needed for high-performance street engines, engine rebuilds, and racing applications. The proprietary Duraglide material technology ensures these bearings can withstand extreme loads and temperatures while maintaining proper oil film thickness.
