ACL Bearings 6B4380H-STD Race Series Rod Bearing Set Ford 3.5L EcoBoost V6

The ACL Bearings 6B4380H-STD is a high-performance connecting rod bearing set engineered specifically for Ford 3.5L EcoBoost V6 engines. Part of ACL's renowned Race Series lineup, these bearings are designed to withstand extreme conditions and high-load applications found in turbocharged performance engines.

Race Series Performance Features:

• High-strength overlay plate with reduced thickness for improved fatigue resistance
• Hardened steel backing on all rod bearings for superior lining support and retention
• Increased crush design ensures optimal bearing retention in the housing
• Enhanced eccentricity compensates for bore distortion at high RPM and promotes hydrodynamic oil film formation
• Elimination of flash plating on bearing backs improves heat transfer and maximizes grip
• Tight, consistent wall thickness tolerances maintain precise clearances
• Standard size (STD) for OE crankshaft journal dimensions

ACL Race Series bearings utilize advanced trimetal construction and precise geometric design that allows them to adapt to the deformations occurring at high RPM. This technology, combined with exacting manufacturing tolerances, makes these bearings ideal for high-horsepower EcoBoost builds, forced induction applications, and demanding motorsports use. These bearings have proven their reliability in race engines from sport compact drifting to professional racing competitions.
