8.8-inch Ford F-150 Differential Cover

The Zumbrota Drivetrain RAA435-2026D is a remanufactured axle assembly meticulously rebuilt to the highest standards of precision and reliability for specific Ford F-150 models. This unit features a Ford 8.8-inch ring gear and a 3.31 gear ratio, tailored for 2000 F-150s equipped with rear disc brakes. The assembly is designed without Posi Traction, and it includes the differential cover, though fluid is not supplied. Each Zumbrota axle assembly undergoes a rigorous inspection process. This includes checking for straightness, cracks, and surface wear. All internal components such as ring and pinions, internal gears, and carriers are thoroughly inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and gears are inspected for proper tooth contact patterns and rolling torque using inch-pound measurements. The gear backlash is precisely set for correct lubrication and quiet operation, while axle tubes are verified to meet OEM standards for straightness. Zumbrota employs a specialized cleaning procedure, including hydro-blasting and sandblasting, followed by a proprietary deep cleaning process that sets a high standard for remanufactured axle assemblies. The HOLLANDER number for this unit is 435-226D. This axle assembly is a semi-floating type.
