Description

The Zumbrota Drivetrain NTC273D-4 is a new NP273 transfer case specifically engineered for 2006-2012 Ram 2500 and 3500 trucks. This unit features a 29-spline input shaft with a 1.55-inch exposed length and a 34-spline rear output designed in a slip yoke style. It is designed without a speedo hole and utilizes ATF +4 fluid, requiring a capacity of 2 quarts. The shift motor is not included with this transfer case. Zumbrota Drivetrain emphasizes quality in their rebuilt units, ensuring confidence and satisfaction. Each transfer case is meticulously inspected, with cases and internal components checked for wear, including cracks, stripped threads, shaft straightness, gear wear, and chain stretch. They employ an exclusive Hydro-blast rinse and blasting procedure, followed by a proprietary deep cleaning process. The unit is fully rebuilt with all new bearings and seals, and viscous couplers are replaced as needed. Finished units are thoroughly spun tested for proper shiftability and noise levels before being shipped in high-density plastic totes to prevent in-transit damage. This transfer case requires a $600 core charge, which is refundable upon the return of your old, salvageable part for recycling or rebuilding. Zumbrota Drivetrain offers various shipping options, including same-day dispatch for eligible orders and free shipping on orders over $199, with specific rates for reman parts.
