AAM 11.5" Rear Axle Assembly 3.42 Ratio Posi-traction

The Zumbrota Drivetrain RAA435-2159E is a remanufactured AAM 11.5" axle assembly designed for 2004-2007 Chrysler Ram 2500 and SRW 3500 models equipped with 4WD and a 3.42 ratio. This axle assembly is rebuilt to the highest quality standards, with each component thoroughly inspected for precision and reliability. Internal parts, including ring and pinions, gears, clutches, and carriers, undergo a 100% inspection. All bearings and seals are replaced, and gears are set for optimal tooth contact patterns, correct rolling torque, and proper backlash to ensure quiet operation and longevity. 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 and remanufacturing process ensures that the axle assemblies meet OEM specifications for straightness and surface wear. The 3.42 gear ratio and Posi-traction differential are designed to provide reliable performance for demanding applications.
