NP273 Transfer Case

The Zumbrota Drivetrain RTC273F-5 is a remanufactured NP273 transfer case specifically designed for 2008-2010 Ford F250 and F350 vehicles. This unit is built to rigorous standards, ensuring reliability and confidence for demanding use. The rebuilding process involves thorough inspection and testing of all components, including checks for cracks, stripped threads, shaft straightness, gear wear, and chain stretch. Zumbrota Drivetrain employs an exclusive Hydro-blast rinse and blasting procedure for both internal and external parts, followed by a proprietary deep cleaning process. Each transfer case is fully rebuilt with the replacement of all bearings, seals, and viscous couplers to ensure optimal performance. After rebuilding, every unit undergoes comprehensive spin testing to verify shift-ability and check for any operational noise. Key specifications include a 34-spline input, an electric shift type, and a slip yoke style rear output shaft. The unit also features 3 mounting holes on the rear extension housing. It is identified by Hollander No. 412-633. Zumbrota Drivetrain ensures that all finished units are shipped in high-density plastic totes to prevent damage during transit, providing peace of mind to the end-user.
