NP233 Remanufactured Transfer Case

The Zumbrota Drivetrain RTC233G-3 is a meticulously remanufactured NP233 transfer case engineered for specific 1994 GM S10, Chevrolet Blazer, and GMC Sonoma vehicles equipped with a 32-spline rear output shaft. This unit features electric shift functionality, a slip yoke style rear output shaft, and a slip yoke style front output shaft, along with an electric speed sensor. Zumbrota Drivetrain's remanufacturing process emphasizes quality and durability. Each transfer case is subjected to thorough inspection of its housing and internal components to detect signs of wear such as cracks, stripped threads, shaft straightness issues, gear wear, and chain stretch. A specialized Hydro-blast rinse and blasting procedure is employed, followed by a proprietary deep cleaning process, to restore parts to an OEM finish. Every rebuilt unit includes the replacement of all bearings, seals, and viscous couplers (where applicable). Finished units undergo comprehensive spin testing to ensure proper shiftability and quiet operation. For transportation protection, all transfer cases are shipped in high-density plastic totes to prevent damage during transit. This transfer case comes with a 2-year limited warranty.
