8.8-Inch Rear Axle Assembly with 3.08 Ratio and Posi-Traction

The Zumbrota Drivetrain RAA435-2025B-P is a remanufactured complete axle assembly engineered for the 2000 Ford F-150. This unit is built to precise standards, ensuring reliability and optimal performance. It features a 3.08 gear ratio, an 8.8-inch Ford ring gear, rear disc brakes, and Posi-Traction for enhanced grip. During the remanufacturing process, Zumbrota Drivetrain meticulously inspects all components. Axle tubes are checked for straightness to OEM specifications, and housings are tested for wear and cracks. Internal parts, including ring and pinions, gears, clutches, and carriers, undergo a 100% inspection. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced to guarantee longevity and proper function. The gears are set for optimal tooth contact patterns and correct rolling torque using inch-pound measurements, with backlash precisely set for lubrication and quiet operation. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-peening deep cleaning process, setting a high standard for axle assembly remanufacturing. This assembly does not include hubs, brakes, backing plates, or axle shafts; these components will need to be sourced separately if not already present.
