{"product_id":"3-21-ratio-12-bolt-posi-traction-axle-assembly","title":"3.21 Ratio 12-Bolt Posi Traction Axle Assembly","description":"The Zumbrota Drivetrain RAA435-167A-P is a remanufactured complete axle assembly built to high standards of precision and reliability. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring \u0026amp; pinions, internal gears, clutches, and carriers, are fully inspected and tested. All bearings and seals are replaced, and gears are examined for optimal tooth contact patterns and set to correct rolling torque using inch-pound measurements for precise setup and longevity. Proper gear backlash is also set to ensure adequate lubrication and quiet operation.\n\nThe axle tubes are 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, establishing a benchmark for axle assembly remanufacturing. The 9.25-inch axle assembly has a 3.21 gear ratio, a 12-bolt hexagon cover, and features Posi Traction. It is specifically designed for 2009-2010 Dodge Ram 1500 models with a square brake flange. The original part numbers are 52114915AA and 68040900AA.\n\nThis assembly does not include hubs, brakes, backing plates, or axle shafts. It comes with a 2-year limited warranty.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870764298552,"sku":"RAA435-167A-P","price":3450.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-21-ratio-12-bolt-posi-traction-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
