Remanufactured Axle Assembly 3.42 Ratio G80 Posi Traction

The Zumbrota Drivetrain RAA435-1870 is a remanufactured axle assembly built to precise quality standards for GM 9.5-inch rear differentials. This unit is specifically designed for 1996-2002 GM Van 2500 applications, featuring a 3.42 gear ratio and Posi Traction with a G80 locking differential. Each axle assembly undergoes a rigorous remanufacturing process. This includes thorough inspection of all internal components such as ring and pinions, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and set to precise rolling torque specifications, ensuring proper gear lubrication, quiet operation, and longevity. Housings are inspected for cracks and surface wear, and tubes are checked for OEM straightness. Zumbrota employs a proprietary cleaning process, including hydro-blasting and sandblasting, to restore housings to an OEM finish. This specific assembly is configured with a 3.42 gear ratio for the GM 14 Bolt 9.5 Inch ring gear, utilizes 6 Lug Semi-Float Axles, and is compatible with 11 Inch Brakes. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately.
