Remanufactured NP231 Transfer Case

The Zumbrota Drivetrain NP231 transfer case, model RTC231G-2, is a remanufactured unit specifically built for 1998 GM S10 and S15 vehicles. This transfer case is engineered with a 27-spline slip yoke style rear output and a bolt-on front output yoke, ensuring a robust connection for your drivetrain. This unit is equipped with features such as a wire or vacuum style shift indicator switch and a provision for a speed sensor. Zumbrota Drivetrain emphasizes unparalleled standards in their remanufacturing process. Each transfer case undergoes thorough inspection for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. Internal and external components are meticulously cleaned using a hydro-blast rinse and blasting procedure, followed by a proprietary deep cleaning. All units are rebuilt with the replacement of all bearings, seals, and viscous couplers. Each finished transfer case is thoroughly spun tested to verify shift-ability and ensure quiet operation. To prevent damage during transit, all transfer cases are shipped in high-density plastic totes. This remanufactured transfer case comes with a 2-year limited warranty.
