Description

The Zumbrota Drivetrain RAA435-204H-P is a meticulously remanufactured complete axle assembly designed for the Ford F-350 Super Duty models from 2013 to 2016. This full-floating axle assembly is built to meet stringent quality standards, ensuring reliability and performance for heavy-duty applications. Each axle assembly undergoes a comprehensive inspection and remanufacturing process. This includes a thorough evaluation of axle tubes for straightness, cracks, and surface wear, along with a 100% inspection of all internal components such as ring and pinions, internal gears, clutches, and carriers. To guarantee optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The assembly is set up with the correct rolling torque and gear backlash for efficient lubrication and quiet operation. An advanced cleaning process, including hydro-blast rinsing and sandblasting, is applied to both internal and external components. A proprietary shot-enticed deep cleaning method is used to restore the cases to an OEM finish. The specifications for this unit include a full-floating axle type, a Dana 80 differential, a 4.11 gear ratio, and a Posi Limited Slip Differential (LSD). A cover is included, but fluid is not. This axle assembly is designed to meet OEM specifications and is an excellent choice for those seeking to maintain their Ford F-350's performance under demanding conditions. The shipping fee covers transportation and the return of your core to the manufacturer.
