Dana 60 Front Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain RAA434-118E is a remanufactured Dana 60 front axle assembly, engineered for 2008-2010 Ford F350 trucks with Dual Rear Wheels (DRW) and without the Wide Track (Fatboy) option. This assembly features a 3.73 gear ratio and a substantial 9.75-inch ring gear, ensuring robust performance for heavy-duty applications. This unit includes the main housing and all internal components, but notably excludes axles, ball joints, spindles, steering components, and brakes, allowing for customization based on specific build needs. Zumbrota Drivetrain employs rigorous remanufacturing processes. All axle tubes are inspected and straightened to meet OEM specifications, and housings undergo thorough testing for surface wear and cracks to ensure structural integrity. Internally, every component, including the ring and pinion gears, internal gears, clutches, and carriers, receives a 100% inspection. To guarantee longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The assembly process includes establishing correct rolling torque using precise inch-pound measurements and setting proper gear backlash for quiet operation and adequate lubrication. Zumbrota also utilizes a state-of-the-art hydro-blasting and rinsing process for a like-new finish on all housings.
