Remanufactured NP241 Transfer Case

The Zumbrota Drivetrain RTC241DHD-4 is a meticulously remanufactured NP241 transfer case, built to the highest standards for demanding applications. This unit is specifically designed for 1997 Dodge Ram 3500 4WD models equipped with a manual transmission. This transfer case features a 29-spline input shaft with a 0.84-inch exposed length, a circular front output yoke, and a PTO opening. The rear output shaft is a 31-spline slip yoke style, measuring 1.608 inches in outside diameter. It also includes a speedo hole. Zumbrota transfer cases are rebuilt by craftsmen with over 150 years of combined industry experience. Each unit undergoes rigorous inspection for wear, including cracks, stripped threads, shaft warp, gear wear, and chain stretch. All internal components are replaced with new bearings, seals, and viscous couplers. The rebuilding process includes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning. Every finished unit is thoroughly spin tested for proper shiftability and noise reduction before being shipped in protective high-density plastic totes to ensure safe transit. A standard 2-year, unlimited mileage warranty backs this transfer case, providing confidence and peace of mind.
