{"product_id":"ford-8-8-3-55-ratio-axle-assembly","title":"Ford 8.8\" 3.55 Ratio Axle Assembly","description":"The Zumbrota Drivetrain RAA435-2164E is a remanufactured axle assembly built to precise OEM specifications for Ford 8.8\" differentials. This unit is designed for 2003-2005 Ford Town Car models featuring ABS and Posi-Traction, with a 3.55 gear ratio.\n\nEach axle assembly undergoes rigorous inspection of all components, including housing straightness, cracks, surface wear, and internal parts like ring and pinions, gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The remanufacturing process includes straightening axle tubes to OEM specifications, ensuring correct rolling torque with inch-pound measurements for setup and longevity, and setting proper gear backlash for optimal lubrication and quiet operation. Zumbrota utilizes a state-of-the-art hydro-blasting and sandblasting procedure for cleaning, restoring housings to an OEM finish.\n\nThis assembly includes a 3.55 ratio, an 8.8-inch ring gear diameter, 31 spline axles, and the axle cover. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts. If the original vehicle was equipped with 28 spline axles, an upgrade to 31 spline axles will be necessary. This unit is a standard replacement grade type and does not come pre-filled with fluid.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870881706296,"sku":"RAA435-2164E","price":2350.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/ford-8-8-3-55-ratio-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
