Remanufactured Axle Assembly 3.73 Ratio AAM 11.5" Ring Gear

The Zumbrota Drivetrain RAA435-130A is a remanufactured axle assembly meticulously rebuilt for 2007-2008 Dodge Ram 3500 Cab Chassis vehicles equipped with dual rear wheels. This unit features a 3.73 gear ratio and utilizes an AAM 11.5-inch ring gear. Each assembly is subjected to rigorous inspection and refurbishment processes. All tubes are verified to be straightened to OEM specifications, and housings are thoroughly tested for surface wear and cracks. Internally, a 100% inspection is performed on all components, including the ring and pinion, internal gears, clutches, and carriers. Critically, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts to ensure longevity and performance. The housing is then cleaned via a state-of-the-art hydro blasting and rinsing process, restoring it to its original OEM finish. It is configured for vehicles without Posi-Traction but does include brakes and backing plates. The assembly is compatible with both 2WD and 4WD configurations. Note that axle shafts are not included with this assembly.
