Description

The Zumbrota Drivetrain RAA435-2180B is a remanufactured axle assembly designed for Dana 60 applications, offering a precise 4.10 gear ratio and a 9.75-inch ring gear. This unit is engineered for vehicles with an 8500 or 8600 GVW rating and comes equipped with Posi traction while excluding active brake control. The process includes thorough inspection of all tubes for straightness and housings for wear and cracks. Internals such as the ring and pinion, gears, clutches, and carriers are subjected to 100% inspection. To guarantee longevity and performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housings are hydro-blasted for an OEM finish, and rolling torque is precisely set using inch-pound measurements for optimal setup and durability. This semi-floating axle assembly includes the cover but does not include hubs, brakes, backing plates, or axle shafts, requiring these components to be sourced separately. It is specifically designed for the 2003-2009 Chevrolet Express 2500 and GMC Savana 2500 models. Users are advised to confirm fluid is not included and to purchase it prior to installation. Zumbrota Drivetrain emphasizes rigorous quality control throughout the remanufacturing process. Their procedures ensure that all components meet or exceed OEM specifications for performance and fitment, providing a dependable replacement for your vehicle's drivetrain.
