{"product_id":"dana-60-rear-axle-assembly","title":"Dana 60 Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-1230B is a meticulously remanufactured axle assembly built for the robust Dana 60 rear axle. This unit is engineered with a 9.75-inch ring gear and a 4.10 gear ratio, ensuring optimal performance for specific applications. It is designed for 1980-1988 Chrysler Dodge D250, W250, and W350 models.\n\nEach Zumbrota axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. The process includes thorough inspection for straightness, cracks, and surface wear. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. Crucially, all bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct rolling torque with inch-pound measurements to ensure precise setup and longevity. Gear backlash is set to factory specifications for proper lubrication and quiet operation, and axle tubes are inspected to ensure OEM standards of straightness.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-peening deep cleaning process. This comprehensive approach sets a high standard for axle assembly remanufacturing, aiming for durability and quiet operation.\n\nKey specifications include a 9.75-inch ring gear size, Dana 60 model, 4.1 ratio (also listed as 4.10), a 10-bolt cover bolt pattern, and a full-floating axle type. The assembly comes with the cover included but does not include fluid. It is explicitly stated as being 'Without Posi', meaning it is not equipped with a limited-slip or locking differential.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870736412984,"sku":"RAA435-1230B","price":1438.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/dana-60-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
