Dana 80 Posi Traction Rear Axle Assembly

The Zumbrota Drivetrain RAA435-1841A-P is a remanufactured axle assembly specifically engineered for the Dana 80 axle, featuring a 4.63 gear ratio and a Posi Traction differential. This unit is built to stringent quality standards, ensuring precision and reliability for your vehicle's drivetrain. During the remanufacturing process, all axle tubes are inspected and straightened to OEM specifications. Housings are thoroughly tested for surface wear and cracks to guarantee structural integrity. Internal components, including the ring and pinion gears, differential gears, and clutch packs, receive a 100% inspection. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings are cleaned using an advanced hydro blasting and rinsing process to restore them to their original OEM finish, and correct rolling torque is meticulously established using inch-pound measurements for a precise setup. This specific axle assembly is designed for 1992-2002 GM 3500HD models with a 4.63 ratio, configured for 2WD, Dual Rear Wheels (DRW), and Wide Track options. It is equipped with the G80 Posi Traction differential. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. A refundable core charge applies to this remanufactured part.
