It features a 3.31 gear ratio, a Ford 8.8-inch ring gear, and is configured for rear drum brakes. This assembly comes equipped with a Posi-Traction limited-slip differential (LSD) to enhance traction.\n\nDuring the remanufacturing process, each axle assembly is meticulously inspected for critical elements like straightness, cracks, and surface wear to ensure structural integrity. Internally, all components, including the ring and pinion gears, clutches, and carriers, undergo comprehensive inspection and testing. To guarantee performance and longevity, all bearings and seals are replaced with new parts. The gears are carefully examined for optimal tooth contact patterns, and rolling torque is precisely set using inch-pound measurements.\n\nZumbrota Drivetrain employs an exclusive hydro-blast and sandblasting procedure for cleaning internal and external parts, followed by a proprietary deep cleaning process. This thorough cleaning brings the housings back to OEM finish standards. The process also includes inspecting axle tubes to ensure they meet OEM specifications for straightness, and all housings are tested for surface wear and cracks.\n\nImportant technical notes specify that this assembly does not include hubs, brakes, backing plates, or axle shafts. The tag number for this specific unit is S826B. It is essential to check the tag number on your original differential to ensure compatibility.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870837403960,"sku":"RAA435-2037C-P","price":2457.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-rear-axle-assembly-3-31-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
