Remanufactured Axle Assembly 3.21 Posi Traction

The Zumbrota Drivetrain RAA435-167A is a remanufactured complete axle assembly engineered for Chrysler 9.25-inch differentials. This unit is equipped with a 3.21 gear ratio and a Posi Traction limited-slip differential, offering enhanced traction capabilities. During the remanufacturing process, Zumbrota Drivetrain meticulously inspects all internal components, including ring and pinions, internal gears, clutches, and carriers. Every bearing, seal, crush sleeve, pinion nut, and shim is replaced to ensure optimal performance and longevity. Gears are set for precise setup, correct rolling torque, and proper backlash, while axle tubes are verified for OEM straightness standards. The cleaning process involves an exclusive hydro-blast rinse, sandblasting, and a proprietary shot-peened deep cleaning method. This axle assembly specifically fits 2009-2010 Dodge Ram 1500 models with a square brake flange. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts; these components must be sourced separately.
