Show original supplier description
The Zumbrota Drivetrain RAA435-2077A-P is a remanufactured axle assembly designed for Dana 70 applications, specifically fitting 2000-2003 Ford E450 models. This unit comes with a 4.10 gear ratio and a Posi Traction differential, offering improved performance and grip. The ring gear measures 10.5 inches. All housings are meticulously cleaned using a hydro blasting process to restore them to OEM finish, and all internal components, bearings, seals, and shims are inspected and replaced as needed to ensure precision setup and longevity. The rolling torque is precisely established using inch-pound measurements. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts. The product is built to order and includes a refundable core charge of $1,000, which is returned upon receipt of your old, salvageable part.
