ACL Bearings 6B2390-1.00 Connecting Rod Bearing Set Standard Size Tri-Metal

The ACL Bearings 6B2390-1.00 is a standard size connecting rod bearing set engineered with tri-metal construction for superior strength and durability. This bearing set features a copper-lead alloy layer with steel backing and electroplated overlay, delivering the ideal combination of strength, conformability, and seizure resistance required for demanding engine applications.

Key Features:

• Tri-metal construction with copper, lead, tin, and nickel for exceptional strength and seizure resistance
• Hardened steel backing provides superior support for the bearing lining and enhances retention in the housing
• High-strength overlay plate with reduced thickness for improved fatigue properties
• Elimination of flash plating on bearing backs to maximize heat transfer and improve grip between bearing and housing
• Tight, consistent wall tolerances to maintain precise clearances
• Enlarged ID chamfers on bearing edges to accommodate large fillet radius on performance crankshafts
• Standard size (1.00) for factory crankshaft journal dimensions
