It features a 3.73 gear ratio and Posi Traction for enhanced performance. The remanufacturing process includes a 100% inspection of all internal parts such as ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housing is inspected for straightness, cracks, and surface wear, and then cleaned using a hydro-blasting and rinsing process to restore it to OEM finish. Correct rolling torque is established using inch-pound measurements for optimal setup and longevity, and gear backlash is set for proper lubrication and quiet operation.\n\nKey specifications include a Dana 80 axle type, 11.25-inch ring gear diameter, and Posi Traction. The assembly includes a new differential cover but does not include hubs, brakes, backing plates, or axle shafts. It is crucial to check the tag numbers (F81A-ARE, F81A-ARF) to ensure compatibility.\n\n*   1999 Ford F-350 Super Duty 5.4L GAS\n*   1999 Ford F-350 Super Duty 6.8L GAS\n*   1999 Ford F-350 Super Duty 7.3L DIESEL\n*   2000 Ford F-350 Super Duty 5.4L GAS\n*   2000 Ford F-350 Super Duty 6.8L GAS\n*   2000 Ford F-350 Super Duty 7.3L DIESEL","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870814990648,"sku":"RAA435-1987A","price":4426.39,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-rear-axle-assembly-dana-80-3-73-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
