Remanufactured Axle Assembly 4.11 Ratio

The Zumbrota Drivetrain RAA435-128B is a remanufactured complete axle assembly for Chrysler 11.5-inch axles. This assembly is designed for 2WD, dual rear wheel (DRW) 2006-2008 Dodge Ram 3500 models featuring a 4.11 gear ratio. It is also specified for some 2007-2008 Ram 3500 models excluding cab-chassis configurations. Zumbrota Drivetrain Axle Assemblies are rebuilt to the highest quality standards, ensuring precision and reliability. Each assembly is thoroughly inspected for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. To guarantee optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are meticulously inspected for ideal tooth contact patterns and set to the correct rolling torque using inch-pound measurements. Axle tubes are also inspected to ensure they meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This rigorous cleaning method sets a high standard for axle assembly remanufacturing, ensuring that housings are returned to an OEM finish and are free from surface wear and cracks. This axle assembly comes with a 1-year limited warranty. A refundable core charge is applied at the time of purchase and will be returned upon the return of your old, salvageable part.
