Description

The Zumbrota Drivetrain RTC273D-4 is a remanufactured NP273 transfer case engineered to be a direct fit for 2006-2012 Dodge Ram 2500 and 3500 models. This unit is suitable for trucks equipped with either a manual transmission or the 6.7L diesel engine paired with an automatic transmission. This transfer case is built with a 34-spline rear slip yoke and a splined shift shaft, ensuring robust engagement. It operates via an electric shift system, though the shift motor is not included. Detailed specifications include a 29-spline input shaft with a 1.55-inch exposed length and the absence of a speedo hole. The unit also retains original tag numbers like 52123025AA, 52123025AB, and 52123025AD, along with Hollander number 412-616. All Zumbrota Drivetrain remanufactured units undergo rigorous quality inspections throughout the rebuilding process to meet high standards. The product listing includes a refundable core charge of $600, which is returned upon receipt of your old, salvageable part. Compatibility is specific to the 2006-2011 Dodge Ram 2500 and 3500, for use with Manual Transmissions or the 6.7L With Automatic Transmission.
