ACL Bearings 8B831A-20 Connecting Rod Bearing Set .020 Undersize

The ACL Bearings 8B831A-20 is a high-performance connecting rod bearing set designed for demanding engine builds and performance applications. This set features .020" (.50mm) undersize bearings to accommodate reground crankshafts, making it an essential component for engine rebuilds and performance upgrades.

Key Features:

• Race Series construction with enhanced material composition for superior strength and durability
• High-strength overlay plate with reduced thickness for improved fatigue resistance
• Hardened steel backing on all bearing shells for enhanced support and retention
• Increased crush height for improved bearing retention in the housing
• Optimized oil grooves and distribution channels for enhanced lubrication
• Superior heat conduction properties for improved thermal management
• Dark electroplated finish indicates race-spec overlay without flash plating for better heat transfer
• .020" undersize for use with reground crankshaft journals

ACL Race Series bearings are engineered to withstand high RPM conditions and increased loads found in performance and racing applications. The precision manufacturing and advanced metallurgy provide the endurance and reliability required when standard bearings simply won't do. Each bearing set is manufactured to exacting tolerances to ensure proper oil clearances and optimal engine performance.
