This assembly comes with a 4.56 gear ratio, identified by the Ratio Option HC4.\n\nZumbrota Drivetrain remanufactures these axle assemblies to high standards of precision and reliability. Each unit undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. Critically, all bearings and seals are replaced as part of the remanufacturing process. The gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and extended longevity. Gear backlash is set correctly to ensure proper lubrication and quiet operation.\n\nThe remanufacturing process employed by Zumbrota includes an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary shot-peening deep cleaning process, setting a high standard for axle assembly remanufacturing. The housings are also tested for surface wear and cracks, and units are shipped in high-density plastic totes to minimize in-transit damage. This assembly includes a pin switch hole by the actuator and two 2-way connectors.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870906773816,"sku":"RAA440-1291D","price":1670.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/9-25-ifs-remanufactured-axle-assembly-4-56-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
