This heavy-duty assembly features a 10.5-inch ring gear and a 3.73 gear ratio, designed for Dual Rear Wheels (DRW) configurations with a straight frame. It comes equipped with the G80 Posi Traction differential for enhanced performance.\n\nEach Zumbrota axle assembly undergoes a rigorous remanufacturing process. All tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. Internal components, including ring and pinions, internal gears, clutches, and carriers, receive 100% inspection. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The assembly is meticulously cleaned using a hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process. Gears are inspected for optimal tooth contact patterns and set to correct rolling torque using inch-pound measurements, with proper backlash set for lubrication and quiet operation, ensuring precision setup and longevity.\n\nIt is intended for trucks with Dual Rear Wheels (DRW) and a straight frame. Importantly, it does not include hubs, brakes, backing plates, or axle shafts. This assembly is explicitly stated to not fit Wide Trac models (GTY option) or Ratio Option GT4.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870762398008,"sku":"RAA435-1658B-P","price":6473.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-complete-axle-assembly-3-73-gear-ratio-drw","provider":"MOTORMIA","version":"1.0","type":"link"}
