Description

The Zumbrota Drivetrain RAA435-264A is a remanufactured axle assembly, meticulously rebuilt to exacting standards for GM 14 Bolt trucks and vans manufactured between 2010 and 2014. This axle assembly features a 3.73 gear ratio and is specifically engineered for Dual Rear Wheel (DRW) configurations with a Cutaway Cab. The remanufacturing process includes thorough inspection and straightening of all tubes to meet OEM specifications, along with testing of housings for surface wear and cracks. Internally, every component, including the Ring & Pinion set, Internal Gears, Clutch assembly, and Carrier, undergoes a 100% inspection. To ensure optimal performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housing is then cleaned using a state-of-the-art hydro blasting and rinsing process, restoring it to the original OEM finish. Finally, precise rolling torque is established using inch-pound measurements for a setup that guarantees longevity and performance. It is important to note that this axle assembly does not include hubs, brakes, backing plates, or axle shafts.
