Ford 8.8-Inch Rear Axle Assembly 3.31 Posi Traction

The Zumbrota Drivetrain RAA435-210C-P is a meticulously remanufactured axle assembly, engineered to meet or exceed OEM standards for Ford 8.8-inch rear differentials. This unit comes with a 3.31 gear ratio and a Posi Traction (Limited Slip Differential) for enhanced traction. During the remanufacturing process, Zumbrota Drivetrain ensures the structural integrity of the housing by inspecting for surface wear and cracks, and straightening tubes to OEM specifications. All internal components, including the ring and pinion gears, internal gears, and clutches, undergo a 100% inspection. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are replaced as needed to guarantee correct rolling torque and precise setup for optimal performance and durability. The housings are also hydro-blasted and rinsed to restore them to an OEM finish. This axle assembly is specifically designed for the 2009-2011 Ford F-150 models. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, and these components will need to be sourced separately if they are not being reused from the original axle. Zumbrota Drivetrain emphasizes quality control through a 100% inspection of all internal parts and ensures correct rolling torque is established using inch-pound measurements for precision setup and longevity.
