{"product_id":"9-75-3-73-posi-traction-rear-axle-assembly","title":"9.75\" 3.73 Posi Traction Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-213B-P is a remanufactured complete axle assembly engineered for Ford 9.75-inch ring gear applications, specifically fitting 2012-2014 Ford F-150 models. This unit comes equipped with a 3.73 gear ratio and 7-lug axles, featuring a Posi Traction limited-slip differential for enhanced traction.\n\nEach axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. Internal components, including ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. All new bearings, seals, crush sleeves, pinion nuts, and shims are installed. The setup ensures optimal gear tooth contact patterns, correct rolling torque measured in inch-pounds for precise setup and longevity, and proper gear backlash for lubrication and quiet operation.\n\nZumbrota Drivetrain utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, to prepare both internal and external parts. Axle tubes are inspected to ensure they are straightened to OEM specifications, and housings are tested for surface wear and cracks. This meticulous attention to detail ensures the quality and performance of each remanufactured assembly.\n\nThis specific axle assembly does not include hubs, brakes, backing plates, or axle shafts. It is designed for the specified F-150 models and is backed by a 2-year limited warranty.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870875414840,"sku":"RAA435-213B-P","price":3205.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/9-75-3-73-posi-traction-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
