Remanufactured Axle Assembly 10.5" Ring Gear 3.73 Ratio

The Zumbrota Drivetrain RAA435-2044C-P is a remanufactured axle assembly designed for specific Ford applications. This unit features a robust 10.5-inch ring gear and a 3.73 gear ratio, equipped with a Posi Limited Slip Differential to improve traction. It is built for full-floating axles and comes with a cover, though fluid is not included. Each Zumbrota axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. The inspection process covers straightness, cracks, and surface wear. Internally, all components, including ring and pinions, gears, clutches, and carriers, are meticulously examined and tested. To ensure longevity and performance, all bearings and seals are replaced. The gears are set up for optimal tooth contact, correct rolling torque measured in inch-pounds, and proper backlash to guarantee adequate lubrication and quiet operation. Axle tubes are verified for OEM straightness standards. Zumbrota employs an exclusive cleaning procedure that includes hydro-blast rinsing and sandblasting of internal and external parts. This is followed by a proprietary shot-peened deep cleaning process, establishing a benchmark for remanufactured axle assemblies. The product is specifically designed for Ford 10.5-inch axles and dual rear wheels, with a 3.73 gear ratio and Posi Traction. It is noted to be excluded from Cab Chassis models. This remanufactured axle assembly is compatible with Ford F-350 Super Duty models from 2000 to 2004. The specific part number is RAA435-2044C-P, and it aligns with Hollander number 435-244C-P.
