Dana 60 Axle Assembly 3.73 Ratio Posi Traction

The Zumbrota Drivetrain RAA435-2180A-P is a remanufactured axle assembly built to high standards of precision and reliability for Dana 60 applications. This unit is designed for 2003-2009 GM Van 2500 models, featuring a 3.73 gear ratio and a 9.75-inch ring gear. It includes a Posi Traction limited-slip differential and is specifically configured for vehicles without active brake control systems. The assembly is rated for an 8500 or 8600 GVW. During the remanufacturing process, Zumbrota Drivetrain ensures the integrity and performance of each axle assembly. All tubes are inspected and straightened to meet OEM specifications, and housings are rigorously tested for surface wear and cracks. A comprehensive 100% inspection is performed on all internal parts, including the ring and pinion, internal gears, clutches, and carrier. To guarantee longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are then cleaned using a state-of-the-art hydro blasting and rinsing process to restore them to an OEM finish, and the correct rolling torque is precisely established using inch-pound measurements. This specific axle assembly, part number RAA435-2180A-P, does not include hubs, brakes, backing plates, or axle shafts, and these components will need to be sourced separately. The unit is built to order and requires confirmation of a refundable core charge, which is applied as an upfront deposit and returned upon receipt of your old, salvageable part for recycling or rebuilding.
