ACL Bearings 6B1385A-.50 Standard Connecting Rod Bearing Set Undersize - 0.50mm

ACL Bearings 6B1385A-.50 Standard Connecting Rod Bearings deliver precision-engineered performance for demanding engine builds. These connecting rod bearings are designed 0.50mm undersize to accommodate reground crankshafts, providing proper clearances for rebuilt engines.

Key Features:

• Tri-metal construction with high-strength overlay for enhanced fatigue resistance
• Hardened steel backing provides superior support and retention under extreme conditions
• Advanced metallurgy ensures optimal heat dissipation and thermal transfer
• Increased crush for improved bearing retention in the housing
• Enlarged ID chamfers accommodate large fillet radii on performance crankshafts
• Engineered oil distribution channels promote proper lubrication

ACL bearings feature superior material composition, optimized dynamic thickness, and enhanced heat conduction properties compared to standard bearings. The elimination of flash plating on the bearing backs improves heat transfer between the bearing and housing. These bearings are suitable for street performance, racing applications, and engine rebuilds requiring undersized bearings for machined crankshafts.
