{"product_id":"3-73-posi-traction-axle-assembly","title":"3.73 Posi-Traction Axle Assembly","description":"The Zumbrota Drivetrain RAA435-125A-P is a remanufactured axle assembly designed for specific 2006-2008 Dodge Ram 1500 Mega Cab and 2500 models, excluding Power Wagon variants. This assembly is equipped with a 3.73 gear ratio and a posi-traction (limited-slip differential) for improved traction and performance.\n\nEach Zumbrota axle assembly undergoes a rigorous remanufacturing process to ensure precision and reliability. This includes thorough inspection of the housing for straightness, cracks, and surface wear. All internal components, such as ring and pinions, gears, clutches, and carriers, are inspected and tested. To guarantee longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gear setup involves precise adjustment of tooth contact patterns, rolling torque (measured in inch-pounds), and backlash for proper lubrication and quiet operation.\n\nZumbrota employs an exclusive cleaning process that includes hydro-blasting and sandblasting, followed by a proprietary shot-peening deep cleaning method for both internal and external parts, which restores the housing to an OEM finish. This axle assembly does not include hubs, brakes, backing plates, or axle shafts, and is intended for 4WD applications.\n\nFitment is specifically for 2006-2008 Dodge Ram 1500 Mega Cab and 2500 models, excluding the Power Wagon trim. It is confirmed to be for 4WD vehicles with Posi Traction.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870738182456,"sku":"RAA435-125A-P","price":3499.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-73-posi-traction-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
