AAM 11.5" Axle Assembly 4.10 Ratio

The Zumbrota Drivetrain AAM 11.5" Axle Assembly is a meticulously remanufactured unit designed for 2012 Ram 2500 and 3500 Single Rear Wheel (SRW), 4-Wheel Drive (4WD) models featuring a 4.10 gear ratio and Posi-traction differential. This assembly is built to the highest quality standards, incorporating a comprehensive inspection of all internal parts, including the ring and pinion, internal gears, clutches, and carrier. To ensure optimal performance and longevity, Zumbrota Drivetrain performs a 100% replacement of all bearings, seals, crush sleeves, pinion nuts, and shims. Furthermore, all housing tubes are inspected and straightened to meet OEM specifications, and the housings themselves are tested for surface wear and cracks. Our state-of-the-art hydro blasting and rinsing process is used to clean all housings, restoring them to their original OEM finish. The precision setup is confirmed by establishing the correct rolling torque, measured in inch-pounds, guaranteeing precision setup and extended durability for your drivetrain. This product is built to order and ships when ready, with options for expedited shipping. A refundable core charge applies, which is returned upon receipt of your old, salvageable part for recycling or rebuilding.
