AAM 11.5-inch Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain RAA435-2161C-P is a remanufactured AAM 11.5-inch axle assembly designed for precision and reliability. This unit features a 3.73 gear ratio and is equipped with Posi-Traction for enhanced performance. The axle assembly is a full-floating type and comes with the differential cover included. During the remanufacturing process, Zumbrota Drivetrain meticulously inspects each axle assembly for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, undergo thorough inspection and testing. To ensure optimal longevity and quiet operation, all bearings and seals are replaced, and gears are checked for proper tooth contact patterns and rolling torque. The axle tubes are also inspected to meet OEM standards for straightness. Zumbrota employs a specialized hydro-blast rinse, sandblasting, and proprietary shot-peened deep cleaning procedure for its internal and external parts, setting a high standard for axle assembly remanufacturing. This axle assembly is specifically designed for 2004-2005 Dodge Ram 3500 trucks with Dual Rear Wheels (DRW) and a 2WD configuration, featuring the 5.7L engine. It also fits 1989-2002 Dodge trucks equipped with a 5.9L Cummins engine. The AAM 11.5-inch ring gear is a key component of this assembly.
