{"product_id":"remanufactured-axle-assembly-3-31-ratio-3","title":"Remanufactured Axle Assembly 3.31 Ratio","description":"The Zumbrota Drivetrain RAA435-212G-P is a remanufactured axle assembly specifically engineered for 2012-2013 Ford F-150 models. This unit features a 3.31 gear ratio paired with a robust Ford 9.75-inch ring gear and 6-lug axles, ensuring compatibility with the specified F-150 configurations.\n\nEquipped with a Posi-traction (limited-slip differential) system, this assembly enhances traction and performance, particularly in low-grip conditions. It is important to note that this axle assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. The remanufacturing process involves rigorous inspection and refurbishment, including straightening of all tubes to OEM specifications and testing housings for any surface wear or cracks.\n\nEvery internal component, such as the ring and pinion gears, internal gears, clutches, and carrier, is subjected to a comprehensive 100% inspection. To ensure longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housing is meticulously cleaned using a state-of-the-art hydro blasting and rinsing process, restoring it to an OEM finish. Furthermore, the correct rolling torque is precisely established using inch-pound measurements to guarantee precision setup and extend the lifespan of the assembly.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870874366264,"sku":"RAA435-212G-P","price":3239.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-axle-assembly-3-31-ratio-3","provider":"MOTORMIA","version":"1.0","type":"link"}
