Dana 80 4.30 Posi Traction Rear Axle Assembly

The Zumbrota Drivetrain RAA435-158C-P is a remanufactured complete axle assembly designed for the Dana 80 axle platform, specifically for 2005-2007 Ford F350 Pickup models with dual rear wheels (DRW) and a 5.4L engine. This axle assembly has been rebuilt to stringent quality standards. It includes a 4.30 gear ratio and Posi Traction differential. Zumbrota Drivetrain meticulously inspects all internal components, including ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are inspected for optimal tooth contact patterns and correct rolling torque, with gear backlash precisely set to ensure proper lubrication and quiet operation. The remanufacturing process involves thorough inspection of axle tubes for straightness to OEM specifications and testing of housings for surface wear and cracks. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning, to restore housings to an OEM finish. This comprehensive approach ensures the reliability and longevity of the axle assembly. This specific axle assembly does not include hubs, brakes, backing plates, or axle shafts. It is built to order and comes with a 1-year limited warranty.
