NP231 27-Spline Input Transfer Case

The Zumbrota Drivetrain RTC231D-9 is a remanufactured NP231 transfer case engineered specifically for 1998-2001 Chrysler Ram 1500 vehicles equipped with a manual transmission. This unit features a 27-spline input shaft with a 1.55-inch exposed length, a 32-spline rear output shaft, and a flat circular front output yoke. Notably, it is designed without a speedometer drive, and the shift indicator switch is positioned above the shift shaft. Zumbrota Drivetrain emphasizes the quality and reliability of their remanufactured units. Each transfer case is meticulously inspected for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. The remanufacturing process includes a proprietary Hydro-blast rinse and blasting procedure, followed by deep cleaning. All internal components are replaced, including bearings, seals, and viscous couplers. Finished units are thoroughly spun tested for shift-ability and noise, and are shipped in protective high-density plastic totes to prevent transit damage. This specific transfer case model is the New Process 231. Fitment is confirmed for 1998-2001 Chrysler Ram 1500 models with a manual transmission.
