Description

The Zumbrota Drivetrain RAA435-2159G-P is a remanufactured AAM 11.5" axle assembly specifically built for 2008 Chrysler Ram 1500 Mega Cab, 2500, and SRW 3500 models equipped with 4WD and a Posi-traction differential. This unit features a 4.10 gear ratio. Each axle assembly is rebuilt to rigorous standards. All tubes are inspected and straightened to OEM specifications, and housings are tested for wear and cracks. Internals, including the ring and pinion, gears, clutches, and carriers, undergo a 100% inspection. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are all replaced. The housing is then cleaned via a state-of-the-art hydro blasting and rinsing process to achieve an OEM finish, and correct rolling torque is established for precision setup and longevity. This product includes a refundable core charge of +$1,000, which is a deposit for your old, salvageable part that is returned for recycling or rebuilding.
