{"product_id":"3-31-ratio-posi-traction-differential-assembly","title":"3.31 Ratio Posi Traction Differential Assembly","description":"The Zumbrota Drivetrain RAA435-2025C is a remanufactured axle assembly designed with precision and reliability in mind. All tubes are inspected and straightened to OEM specifications, and housings undergo testing for surface wear and cracks. Internal components, including ring and pinion gears, internal gears, clutches, and carriers, are subjected to a 100% inspection.\n\nKey specifications for this assembly include a 3.31 gear ratio, a Ford 8.8-inch ring gear, rear drum brakes, and Posi traction. The unit comes with tag number S826D but does not include hubs, brakes, backing plates, or axle shafts, necessitating their separate sourcing or reuse from the original vehicle.\n\nDuring the remanufacturing process, Zumbrota Drivetrain ensures 100% replacement of all bearings, seals, crush sleeves, pinion nuts, and shims. Housings are cleaned using a state-of-the-art hydro blasting and rinsing process to restore them to their OEM finish. The assembly is set up with the correct rolling torque, established using inch-pound measurements for optimal precision, setup, and longevity.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870824493368,"sku":"RAA435-2025C","price":1999.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-31-ratio-posi-traction-differential-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
