{"product_id":"10-5-inch-4-11-ratio-rear-axle-assembly","title":"10.5-Inch 4.11 Ratio Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-1979B is a remanufactured axle assembly designed for Ford 10.5-inch ring gear differentials, featuring a 4.11 gear ratio and intended for Dual Rear Wheel (DRW) applications. This unit is specifically noted to be for 1999-2000 Ford F-350 models, excluding Cab Chassis and non-Posi Traction configurations.\n\nZumbrota Drivetrain prides itself on rebuilding axle assemblies to the highest standards of precision and reliability. Each assembly undergoes rigorous inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To ensure longevity and performance, all bearings and seals are replaced. Gears are meticulously inspected for optimal tooth contact patterns and set to correct rolling torque using inch-pound measurements. Proper gear backlash is established for adequate lubrication and quiet operation, and axle tubes are verified for OEM straightness standards.\n\nThe remanufacturing process employed by Zumbrota includes an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts. This is followed by a proprietary shot-enticed deep cleaning process, setting a high standard in axle assembly remanufacturing.\n\nKey specifications include a 10.5-inch ring gear diameter, a 4.11 gear ratio, and a full-floating axle type. A differential cover is included, but fluid is not. It is important to note that this axle assembly is for applications without Posi Traction and excludes Cab Chassis models. The \"*Check Tag*\" designation in the product title advises buyers to verify specific vehicle tags for compatibility.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870811353400,"sku":"RAA435-1979B","price":4060.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/10-5-inch-4-11-ratio-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
