{"product_id":"remanufactured-differential-housing-3-21-ratio","title":"Remanufactured Differential Housing 3.21 Ratio","description":"The Zumbrota Drivetrain RAA435-122A is a remanufactured complete axle assembly meticulously rebuilt to exacting standards for the 2007-2008 Dodge Ram 1500. This assembly features a 3.21 gear ratio and a robust Chrysler 9.25 inch ring gear, designed to restore optimal drivetrain performance.\n\nEach axle assembly undergoes a comprehensive inspection process, including checks for straightness, cracks, and surface wear. All internal components, such as ring and pinions, gears, clutches, and carriers, are fully inspected and tested. Zumbrota replaces all bearings and seals, and carefully sets gear backlash for proper lubrication and quiet operation. The process includes a proprietary hydro-blast rinse, sandblasting, and shot-peening for superior cleaning and preparation of internal and external parts.\n\nThis specific axle assembly is for 2WD models and includes a square brake mounting flange and Electronic Stability Program (ESP). It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts. It is also explicitly stated that this assembly does not fit Mega Cab models.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870735987000,"sku":"RAA435-122A","price":2564.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-differential-housing-3-21-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
