4.10 Ratio 8.8-Inch Ring Gear Front Axle Assembly

The Zumbrota Drivetrain RAA440-116C is a fully remanufactured axle assembly designed for 2006-2008 Ford F-150 models equipped with an 8.8-inch Independent Front Suspension (IFS). This unit comes with a 4.10 gear ratio, ensuring optimal performance for specific applications. Each axle assembly is rebuilt to stringent quality standards. The remanufacturing process involves a thorough inspection of all components, including the housing for straightness, cracks, and surface wear. Internal parts such as ring and pinions, gears, clutches, and carriers are 100% inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are precisely set for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for longevity and quiet operation. The axle tubes are also checked to meet OEM straightness standards. Zumbrota Drivetrain employs a proprietary cleaning process, including hydro-blasting and sandblasting, followed by a deep cleaning procedure. This meticulous approach ensures that all components are returned to an OEM finish. Units are shipped in high-density plastic totes to prevent damage during transit. The assembly is backed by a 2-year limited warranty.
