GM 8.6" Axle Assembly 3.42 Ratio G80 Posi

The Zumbrota Drivetrain RAA435-2176A-P is a remanufactured axle assembly engineered for 2003-2005 GMC 1500 2WD vehicles. This unit is built with a 3.42 gear ratio and features the GM 10 Bolt 8.6 Inch ring gear, along with the G80 Posi Traction differential and JL4 active brake control option. Each axle assembly undergoes rigorous inspection processes. All tubes are straightened to OEM specifications and tested for surface wear and cracks. Internal components, including the ring & pinion, gears, and clutch/carrier assemblies, are 100% inspected and tested. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts to ensure longevity and proper function. The housings are professionally cleaned using a state-of-the-art hydro blasting process to restore them to an OEM finish. Correct rolling torque is precisely established using inch-pound measurements during assembly. Please note that this axle assembly does not include hubs, brakes, backing plates, or axle shafts, which may need to be sourced separately. This remanufactured assembly is built to order and ships when ready, with estimated 1-2 day delivery for most locations.
