This unit boasts a robust AAM 10.5-inch ring gear and a 4.10 gear ratio, incorporating the G80 Posi Traction system for enhanced traction. It also features the JL4 Active Brake Control option and a full-floating axle design. The inspection cover is present but lacks a filler plug.\n\nZumbrota Drivetrain emphasizes precision and reliability in their remanufacturing process. Each axle assembly undergoes a thorough inspection for structural integrity, including checks for straightness, cracks, and surface wear. All internal components, such as ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and gears are checked for proper tooth contact patterns and rolling torque. Gear backlash is set correctly for adequate lubrication and quiet operation. The axle tubes are also inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, setting a high standard for remanufactured axle assemblies.\n\nThis specific assembly includes the differential cover but explicitly excludes hubs, brakes, backing plates, and axle shafts. Buyers should ensure they have these components or source them separately.\n\nFitment is confirmed for Chevrolet Silverado 2500HD and GMC Sierra 2500HD models, with specific years often indicated as 2011-2016 in some listings.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870904611128,"sku":"RAA435-274B","price":2699.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/10-5-rear-axle-assembly-4-10-ratio-g80-posi-traction","provider":"MOTORMIA","version":"1.0","type":"link"}
