The Zumbrota Drivetrain BW4447 Transfer Case is a remanufactured assembly built to ensure reliable performance for demanding applications. This unit is specifically designed for 2013-2018 Ram 3500 Cab Chassis trucks featuring the Aisin transmission. It incorporates a manual shift mechanism, a rear slip yoke, and includes a magnet wire in the rear case with an electrical connection for added functionality. The transfer case is engineered with a 28-spline input and an 8-bolt transmission flange for a precise fit. During the remanufacturing process, Zumbrota Drivetrain emphasizes quality control, with all units undergoing inspection to meet stringent standards. The cases are meticulously cleaned using a state-of-the-art hydro blasting and rinsing process, restoring them to an OEM finish. This attention to detail ensures durability and a like-new appearance. This specific transfer case is noted to fit Ram 3500 4WD models from 2013 to 2018. A notable benefit is its compatibility with 33-inch tires, which can be accommodated with minor trimming, appealing to those looking to enhance their truck's stance. The product also comes with a refundable core charge, allowing customers to return their old, salvageable part for recycling or rebuilding to recoup a deposit.
