14 Bolt Complete Axle Assembly 4.10 Ratio G80

The Zumbrota Drivetrain RAA435-2182B-P is a remanufactured complete axle assembly for GM 14 Bolt trucks, precision-built for durability and reliability. This unit is specifically designed to replace the original axle in 2001-2005 GMC Yukon and Avalanche 1500 4x4 models, featuring a 4.10 gear ratio and a Posi Traction differential with the G80 option for enhanced traction. During the remanufacturing process, Zumbrota Drivetrain performs a thorough inspection of all components, including the housing for straightness, cracks, and surface wear. Internal parts such as ring and pinions, gears, clutches, and carriers are 100% inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced to ensure like-new performance and longevity. The assembly process includes setting correct gear backlash for proper lubrication and quiet operation, and establishing precise rolling torque using inch-pound measurements. Zumbrota employs a proprietary cleaning process, including hydro-blasting and sandblasting, to restore housings to OEM specifications and finish. This axle assembly includes the axle cover but does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. The product comes with a 2-year limited warranty.
