Description

The Zumbrota Drivetrain RAA435-2342A is a remanufactured AAM 11.5-inch rear axle assembly specifically built for 2015-2019 GM Silverado and Sierra 2500 and 3500 models equipped with Single Rear Wheels (SRW). This assembly includes a 3.73 gear ratio and the G80 Posi Traction differential, enhancing traction and performance. Each axle housing undergoes a rigorous cleaning process using state-of-the-art hydro blasting and rinsing, ensuring it is returned to an OEM finish. This meticulous remanufacturing process involves thorough inspection of all internal components, including the ring and pinion gears, for straightness, cracks, and surface wear. This rear axle assembly does not include hubs, brakes, backing plates, or axle shafts, and these components will need to be transferred from the original axle or sourced separately.
