This assembly features a 4.56 gear ratio and a Duragrip limited-slip differential for enhanced traction.\n\nZumbrota Performance Axles are remanufactured to exacting standards, ensuring precision and reliability. Each axle assembly undergoes a comprehensive inspection for straightness, cracks, and surface wear. All internal components, including the ring and pinion, internal gears, clutches, and carriers, are meticulously inspected and tested. New bearings and seals are installed, and gear sets are examined for optimal tooth contact and set to the correct rolling torque. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process to prepare parts for assembly.\n\nThis rear axle assembly is specifically designed for the AAM 11.5 axle. It is compatible with 2003-2008 Ram 3500 Dually models, with an exception for 2007-2008 Cab \u0026amp; Chassis models. It is not pre-filled with oil, requiring you to add your preferred lubricant during installation.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870881050936,"sku":"RAA435-2162X2-P","price":4347.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/aam-11-5-rear-axle-assembly-w-duragrip-limited-slip-diff","provider":"MOTORMIA","version":"1.0","type":"link"}
