This assembly is built with a 3.73 gear ratio, utilizes a Ford 9.75-inch ring gear, and features 12mm wheel studs. It comes equipped with a Posi Traction limited-slip differential for enhanced traction.\n\nZumbrota Drivetrain emphasizes a rigorous remanufacturing process. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested to ensure optimal performance. To guarantee longevity and reliability, all bearings and seals are replaced, and gears are inspected for precise tooth contact patterns and correct rolling torque, measured in inch-pounds. Furthermore, axle tubes are inspected to meet OEM standards for straightness.\n\nThe remanufacturing process includes an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary shot-peening deep cleaning. This comprehensive cleaning process restores housings to their OEM finish. The assembly is precisely set with correct gear backlash to ensure proper gear lubrication and quiet operation. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870838059320,"sku":"RAA435-2040C-P","price":1787.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-73-ratio-9-75-inch-ring-gear-axle-assembly-with-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
