Remanufactured Axle Assembly, 3.08 Ratio, Rear Disc

The Zumbrota Drivetrain RAA435-2026B is a remanufactured complete axle assembly, specifically designed for Ford 8.8-inch rear ends. This unit features a 3.08 gear ratio and is configured for vehicles equipped with rear disc brakes. It is crucial to check the tag number (S852F) to ensure compatibility. These axle assemblies are rebuilt to stringent quality standards, emphasizing precision and reliability. The remanufacturing process involves a comprehensive inspection of all internal components, including ring and pinions, gears, clutches, and carriers, as well as the housing for straightness, cracks, and wear. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. Zumbrota employs an advanced cleaning procedure, including hydro-blasting and sandblasting, followed by a proprietary shot-peening process for superior internal and external surface preparation. Gears are inspected for optimal tooth contact patterns, and backlash is precisely set to ensure proper lubrication and quiet operation. Rolling torque is established using inch-pound measurements for enhanced setup accuracy and extended longevity. This axle assembly is designed without Posi Traction and does not include hubs, brakes, backing plates, or axle shafts. It is a direct fit for the 2000 Ford F-150 model.
