3.73 Ratio Remanufactured Axle Assembly

The Zumbrota Drivetrain RAA440-1350G is a remanufactured axle assembly designed for Ford 8.8 IFS differentials. This assembly is rebuilt to exacting standards, ensuring precision and reliability for your drivetrain. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To guarantee longevity and performance, all bearings and seals are replaced, and gears are checked for optimal tooth contact patterns and correct rolling torque. The assembly features a 3.73 gear ratio, an aluminum cover, and is specifically designed without a vacuum disconnect. Zumbrota Drivetrain employs a proprietary cleaning process, including hydro-blasting and sandblasting, followed by a deep cleaning procedure. This rigorous process ensures internal and external parts meet OEM standards for finish and integrity. This axle assembly is compatible with 1997-2002 Ford Expedition models and 2004 Ford F-150 Heritage 4WD models.
