NP243 Electric Shift Transfer Case 23-Spline Input 32-Spline Output

The Zumbrota Drivetrain RTC243D-2 is a professionally remanufactured NP243 transfer case specifically engineered for the 2006-2012 Dodge Ram 1500. This unit is built to rigorous standards, ensuring reliability and satisfaction for the driver. Crafted with precision, this transfer case is an electric shift model, though the shift motor is not included. It features a 23-spline input shaft with a 0.84-inch exposed length, an external spline front output shaft, and a 32-spline rear output. This particular unit is a 2nd generation case and does not come with a shift indicator switch. Key identifiers include the tag number 52853307AA and Hollander number 412-614. Zumbrota Drivetrain's remanufacturing process involves thorough inspection of all components for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. Internal and external parts undergo an exclusive Hydro-blast rinse and blasting procedure, followed by a proprietary deep cleaning. Every unit is fully rebuilt with the replacement of all bearings, seals, and viscous couplers. Each finished transfer case is spun tested for shift-ability and noise, and then shipped in high-density plastic totes to prevent transit damage.
