ACL Bearings 4B2201-060 Connecting Rod Bearing Set

The ACL Bearings 4B2201-060 is a precision-engineered connecting rod bearing set featuring advanced trimetal construction for enhanced durability and performance. Designed for MG 4-cylinder engines with 998-1098-1275cc displacement from 1956-78, these bearings deliver reliable protection for both street and performance applications.

Advanced Trimetal Construction:

• High-strength steel backing provides superior support and structural integrity
• Copper-lead-tin lining layer offers excellent fatigue strength and conformability
• Lead-tin-copper overlay with reduced thickness for improved seizure resistance and lower friction
• Nickel barrier layer prevents metal migration between layers

Key Features:

• Precision-manufactured to strict tolerances for optimal oil clearance
• Enhanced crush design improves bearing retention and heat dissipation
• Increased eccentricity compensates for bore distortion under load
• Suitable for stock rebuilds and mild performance upgrades

ACL bearings bring race-tested durability and precision engineering, with trimetal design featuring reduced overlay thickness for improved fatigue resistance. The .060 designation indicates specific sizing for this application. Professional installation with proper clearance checking using plastigauge is recommended to ensure optimal bearing performance and engine longevity.
