{"product_id":"3-92-ratio-posi-traction-complete-axle-assembly","title":"3.92 Ratio Posi-Traction Complete Axle Assembly","description":"The Zumbrota Drivetrain RAA435-139B-P is a complete remanufactured axle assembly engineered for 2007-2009 Chrysler Aspen and Durango vehicles equipped with the 8.25-inch axle. This assembly includes a 3.92 gear ratio and a Posi-Traction limited-slip differential, offering enhanced traction and performance.\n\nEach axle assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. Zumbrota Drivetrain thoroughly inspects all components for straightness, cracks, and surface wear. Internal parts, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, with precise setup and longevity ensured by inch-pound measurements. Gear backlash is set correctly for proper lubrication and quiet operation, while axle tubes are checked to meet OEM standards of straightness. The housing undergoes a hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process for a superior finish and durability.\n\nThis axle assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. It is built to order and includes a refundable core charge. Zumbrota Drivetrain backs this component with a 2-year limited warranty.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870740410680,"sku":"RAA435-139B-P","price":3173.49,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-92-ratio-posi-traction-complete-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
