ACL Bearings 8B481A-20 Connecting Rod Bearings .020 Undersize

These bearings feature ACL's A-Series Aluglide construction with .020" undersize for use with reground crankshafts.

Key Features:

• Bi-metal Aluglide construction combining aluminum alloy overlay with hardened steel backing for exceptional strength and heat dissipation
• High-strength steel backing provides superior bearing retention and support under demanding conditions
• Increased crush design improves bearing retention through higher radial contact pressures while enhancing heat transfer
• Increased eccentricity compensates for bore distortion at high RPM and assists in forming hydrodynamic oil film
• No flash plating on bearing backs maximizes heat transfer and improves grip within the housing
• Precision machined to exacting micron tolerances for consistent wall thickness and reliable fitment
• .020" undersize specification for use with reground crankshaft journals

ACL Race Series bearings are manufactured with precision measurement systems that deliver consistent accuracy to critical characteristics. This connecting rod bearing set is engineered to provide reliable performance in both stock replacement and performance applications.
