Remanufactured Axle Assembly 4.10 Gear Ratio

The Zumbrota Drivetrain RAA435-2177B is a remanufactured axle assembly specifically designed for GM 8.6" differentials. This unit is built to exacting standards for 2003-2005 GMC 1500 4x4 vehicles, featuring a 4.10 gear ratio for optimal performance. Each axle assembly is meticulously remanufactured to ensure the highest levels of precision and reliability. Zumbrota Drivetrain inspects all axle tubes for straightness and ensures they meet OEM specifications. Housings are thoroughly tested for surface wear and cracks. Internally, every component, including the ring and pinions, internal gears, clutches, and carriers, undergoes a 100% inspection and testing. To guarantee longevity and quiet operation, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced, and the gears are set with precise backlash and rolling torque measurements. Zumbrota Drivetrain distinguishes its remanufacturing process with an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning. This extensive cleaning process restores internal and external parts to their original OEM finish, setting a benchmark for axle assembly remanufacturing quality. This remanufactured axle assembly comes with a 2-year limited warranty, providing peace of mind for your investment.
