Description

The Zumbrota Drivetrain RAA435-204D-P is a remanufactured axle assembly designed for the Dana 80 rear axle. This unit is specifically built for 2008-2012 Ford F-350 models equipped with Dual Rear Wheels (DRW) and the Cab Chassis configuration. It features a 3.73 gear ratio and a Posi Limited Slip Differential for enhanced traction. The remanufacturing process at Zumbrota Drivetrain involves a comprehensive inspection and component replacement. All axle tubes are straightened to OEM specifications, and housings are checked for surface wear and cracks. Internal parts, including the ring and pinion, internal gears, clutches, and carriers, are 100% inspected. To ensure longevity and performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are cleaned using a hydro-blasting process to restore an OEM finish, and precise setup is achieved through the establishment of correct rolling torque and backlash settings. Key specifications for this axle assembly include an 11.25-inch ring gear diameter and a full-floating axle type. The cover is included, but fluid is not. This unit is designated as a Standard Width Axle Package and is specifically for Cab Chassis models with Dual Rear Wheels.
