Description

The Zumbrota Drivetrain RAA435-2023B is a remanufactured complete axle assembly designed for specific Ford F-150 models. It is built to the highest quality standards for precision and reliability, with all internal components thoroughly inspected and tested. Each axle assembly undergoes a rigorous inspection process, including checks for straightness, cracks, and surface wear. Internal components such as ring and pinions, gears, and clutches are tested, and all bearings and seals are replaced. The gears are inspected for optimal tooth contact patterns and set with precise backlash for longevity and quiet operation. Axle tubes are also inspected to ensure they meet OEM standards for straightness. This specific assembly features a 9.75-inch Ford-built ring gear, a 3.55 gear ratio, and is configured for rear disc brakes. It includes a differential cover but does not include fluid. The axle type is semi-floating, with 12mm wheel studs and 2.533 OD wheel bearings. Notably, this model is specified as 'Without Posi Traction'. The product requires "Check Tag" verification for compatibility. Availability information indicates this item is out of stock and may have special order cancellation or return restrictions.
