{"product_id":"11-5-inch-ring-gear-rear-axle-assembly","title":"11.5-Inch Ring Gear Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-171B-P is a remanufactured rear axle assembly designed for 2009 Ram 2500 and 3500 models with Single Rear Wheels (SRW) and 4x4 configurations. This assembly is built around an AAM 11.5-inch ring gear and a 3.73 gear ratio, incorporating a Posi Limited Slip Differential for enhanced traction.\n\nEach Zumbrota axle assembly undergoes a rigorous remanufacturing process. It is thoroughly inspected for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are inspected and tested. To ensure longevity and reliability, all bearings and seals are replaced, and gears are examined for optimal tooth contact patterns and precise rolling torque settings. Backlash is carefully set for proper gear lubrication and quiet operation, while axle tubes are checked for OEM standards of straightness. Zumbrota employs a unique hydro-blast rinse, sandblasting, and proprietary shot-peening deep cleaning procedure for superior internal and external component preparation.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870769738040,"sku":"RAA435-171B-P","price":3909.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/11-5-inch-ring-gear-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
