BW4406 Electric Shift Transfer Case

The Zumbrota Drivetrain BW4406 is a remanufactured transfer case specifically built for electric shift systems in 1999-08 Ford F-150 and 1999 Ford F-250 trucks. Each transfer case is meticulously rebuilt to high standards by expert craftsmen. The process involves a rigorous inspection of internal components for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. Zumbrota Drivetrain employs a proprietary Hydro-blast rinse and blasting procedure, along with a deep cleaning method for both internal and external parts. Critical wear components, such as all bearings, seals, and viscous couplers, are replaced. The remanufacturing process includes quality inspections throughout, and all finished units are spun tested to ensure proper shift-ability and quiet operation. This transfer case is shipped in a high-density plastic tote to prevent damage during transit. Please note that the shift motor is not included with this unit.
