ACL Bearings 6B2150HX-STD Race Series Connecting Rod Bearing Set Standard Size with Extra Oil Clearance

The ACL 6B2150HX-STD is a Race Series connecting rod bearing set designed for Ford 6-cylinder engines including 200-250ci, 3.9L-4.0L OHC, and 4.0L DOHC applications, including popular Ford Barra and Barra Turbo engines. The 'HX' designation signifies this set provides an extra 0.001 inch (0.025mm) oil clearance on a standard size shaft compared to the standard H-STD set, making it ideal for high-performance and racing applications.

Key Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve support of the bearing lining and assist with bearing retention
• Elimination of flash plating on the back of bearings 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
• Manufactured from F781 bearing material with identical bearing halves
• Standard size for use with standard crankshaft journals

ACL bearings are designed for tuning and engine upgrades where superior quality and higher bearing capacity than standard bearings is required, with improvements in material, dynamic thickness, heat conduction, oil grooves and oil distribution. ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, with a unique combination of design, metallurgy and engineering that provides endurance and capability to perform where others cannot.
