This unit is configured for Dual Rear Wheels (DRW) with a Wide Track setup and a Straight Frame, featuring a 3.73 gear ratio.\n\nEach Zumbrota axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. The process includes a comprehensive inspection of the housing for straightness, cracks, and surface wear. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To ensure longevity and optimal function, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are meticulously inspected for proper tooth contact patterns and set to correct rolling torque and backlash using inch-pound measurements.\n\nZumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for both internal and external parts. This ensures a superior clean and finish that meets OEM specifications. While this is a complete axle assembly, it is important to note that it does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately.\n\nThis axle assembly is designed for the specific fitment of 1990-2000 GM 3500 models equipped with Dual Rear Wheels and the Wide Track option, featuring a 3.73 gear ratio and a straight frame. It is not equipped with Posi-Traction.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870762037560,"sku":"RAA435-1657B","price":2564.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-axle-assembly-3-73-ratio-drw-wide-track","provider":"MOTORMIA","version":"1.0","type":"link"}
