{"product_id":"dana-80-rear-axle-assembly-1","title":"Dana 80 Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-1990B-P is a remanufactured Dana 80 axle assembly, precision-built to the highest quality standards for reliability. This unit features a 5.38 gear ratio, a 11.25-inch ring gear, and is designed for dual rear wheels with Posi Traction. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts.\n\nDuring the remanufacturing process, each axle assembly is meticulously inspected for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, undergo rigorous testing. Zumbrota Drivetrain ensures longevity and quiet operation by replacing all bearings and seals, setting correct gear backlash, and verifying optimal tooth contact patterns with precise inch-pound measurements for rolling torque.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary deep cleaning process. This comprehensive cleaning method restores housings to an OEM finish and sets a high standard for axle assembly remanufacturing. All tubes are inspected to ensure they meet OEM standards for straightness.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870817546552,"sku":"RAA435-1990B","price":3799.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/dana-80-rear-axle-assembly-1","provider":"MOTORMIA","version":"1.0","type":"link"}
