{"product_id":"complete-axle-assembly-5-13-ratio","title":"Complete Axle Assembly 5.13 Ratio","description":"The Zumbrota Drivetrain RAA435-1663F is a remanufactured complete axle assembly engineered for 1990-2000 GM 3500 pickup trucks equipped with a 14-bolt, 10.5-inch ring gear and a 5.13 gear ratio. This specific assembly is designed for 2WD Single Rear Wheel (SRW) configurations and explicitly excludes models with wide-track axles.\n\nEach Zumbrota axle assembly undergoes rigorous remanufacturing processes to meet high standards of precision and reliability. This includes thorough inspection of axle tubes for straightness, housing for surface wear and cracks, and all internal components such as ring and pinions, gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gear setup is meticulously performed, with ring and pinion gears inspected for optimal tooth contact patterns, correct rolling torque set using inch-pound measurements for longevity, and proper backlash established for quiet operation and lubrication.\n\nIt is important to note that this axle assembly is designed without posi-traction and does not include essential components such as hubs, brakes, backing plates, or axle shafts. Additionally, it is built for trucks with a GVWR of 9000-9200 lbs.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870763839800,"sku":"RAA435-1663F","price":3584.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/complete-axle-assembly-5-13-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
