The Zumbrota Drivetrain RAA435-2162D-P is a remanufactured AAM 11.5" axle assembly built to restore your heavy-duty truck's drivetrain. This unit is specifically designed for 2004-2008 Chrysler Ram 3500 DRW (Dually) trucks equipped with 4.10 gearing, 4WD, and a Posi (limited-slip) differential. It also accommodates 2007-2008 models excluding the Cab-Chassis configuration. Each Zumbrota axle assembly undergoes a comprehensive remanufacturing process to ensure quality and performance. This includes thorough inspection and straightening of all axle tubes to meet OEM specifications, as well as rigorous testing of housings for surface wear and cracks. Internals such as the ring and pinion, gears, clutch packs, and carriers are subjected to a 100% inspection. To guarantee optimal function and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components. The housing is revitalized through a state-of-the-art hydro blasting and rinsing process, returning it to an OEM finish. Precision is paramount, with correct rolling torque established using inch-pound measurements to ensure both setup accuracy and extended service life. This remanufactured axle assembly is built to provide reliable performance for demanding applications.
