ACL Bearings 4B1060H-001 Race Series Connecting Rod Bearings Ford BDA/BDB .001" Oversize

The ACL Race Series 4B1060H-001 connecting rod bearings are engineered for extreme endurance under harsh conditions, designed specifically for Ford BDA, BDB, BDC, and BDD Cosworth engines. These performance bearings deliver better quality with higher bearing capacity than standard bearings, featuring improvements in material, dynamic thickness, heat conduction, oil grooves, and oil distribution.

Key Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve bearing lining support and bearing retention in the housing
• Increased crush for improved bearing retention
• Elimination of flash plating on the bearing backs to improve heat transfer and maximize grip between bearings and housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• Precision manufactured to exacting tolerances with micron tolerance machining for consistent accuracy in wall thickness and crush

Technical specifications include a maximum shaft size of 49.213mm (1.938"), tunnel size range of 52.927-52.94mm (2.084"), and oil clearance range of 0.034-0.076mm (.001"-.003"). The "001" designation indicates .001" oversize for crankshaft journals. Fatigue, stress wear, and failure are factors you won't have to worry about with ACL's top-tier metallurgy.

Note: Engine bearings require proper tolerance measurement before purchase. Consult a professional engine builder if you are unsure which size bearings your build requires.
