3.92 Ratio Differential Gear Set

The Zumbrota Drivetrain RAA435-2205B is a remanufactured axle assembly designed for specific Dodge Durango models. This assembly is built around a robust Chrysler 9.25-inch ring gear and features a 3.92 gear ratio, suitable for vehicles equipped with 4x4 and traction control. During the remanufacturing process, Zumbrota Drivetrain ensures the highest standards of precision and reliability. Each axle assembly undergoes a thorough inspection for straightness, cracks, and surface wear. Crucially, all internal components, including the ring and pinion gears, internal gears, clutches, and carriers, are meticulously inspected and tested. To guarantee longevity and performance, all bearings and seals are replaced with new ones. The gears are examined for optimal tooth contact patterns, and correct rolling torque is established using inch-pound measurements for precise setup and quiet operation. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peened deep cleaning process. This comprehensive cleaning method ensures that housings are restored to OEM standards of finish and straightness. The assembly includes a cover, but fluid is not included. The axle type is semi-floating. This specific axle assembly is compatible with 2004-2005 Dodge Durango models equipped with 4x4 and traction control.
