About This Unit The BW4446, also written BW44-46, was introduced by BorgWarner in late 2012 as the OEM transfer case for 2013-2018 Dodge RAM 2500 and 3500 trucks equipped with electronic 4WD systems. It replaced the older New Venture NV273 electric-shift unit and represents a more modern, refined design built specifically for the high-torque demands of 4th-generation RAM heavy-duty trucks. The unit features a chain-driven design, an aluminum case housing, a 29-spline input, a 6-bolt adapter pattern, and an electronically controlled shift system that handles 2WD, 4WD-High, Neutral, and 4WD-Low engagement. The BW4446 was offered in multiple factory variations to accommodate different transmission and chassis configurations across the 2013-2018 RAM lineup, including standard pickup, chassis cab, and heavier applications. Tag numbers for the unit run from 5146625AB through 5146625AI depending on production year and configuration. Owners of 4th-gen RAM 2500 and 3500 trucks know the BW4446 as a stout, reliable unit, and our remanufactured version is built to outlast the original factory case while delivering the same OEM-quality fitment, function, and feel.
