About This Unit
The NV273D, also referred to as the NP273D, was introduced as the OEM transfer case for 2003–2012 Dodge Ram 2500 and 3500 models featuring electronic four-wheel drive control. Built for heavy-duty use, it features a robust chain-driven design, a 2.72:1 planetary low-range gear ratio, and die-cast aluminum housing designed to balance strength with weight efficiency.This unit has four variations. Early Model & Late Mode with either a 23-spline or 29-spline input shaft.
Manufacturing originally took place at the New Process Gear plant in East Syracuse, New York, before moving to Mexico around 2010–2011 as part of the transition under New Venture Gear branding. The NP vs. NV prefix reflects this rebranding, but both refer to the same core design. Regardless of the label, the NP273D/NV273D remains a trusted and reliable choice for Dodge diesel truck owners requiring strong off-road performance and drivetrain dependability.
This transfer case is currently on sale — making now the perfect time to replace or upgrade your OEM unit with a fully remanufactured model built to exceed factory standards.
*Note* Please provide us with the Model & Assembly Number when ordering. These numbers are the easiest way to determine which variation you have. Below is an example of where and what to look for highlighted in yellow (This tag is located on the rear half of your transfer case).

Return/Warranty Policy
Are Returns Accepted?
Certainly, you may return an item within 14 days from the date of purchase. However, returns are not permissible if the product has been fitted into a vehicle, or has been altered, modified, or damaged. Refunds issued will not cover the initial shipping fees, and the responsibility for the cost of returning the item to us, which may vary by location and carrier rates, falls on the customer.
Will there be a restocking fee?
To process a return with us, you’ll need to obtain a return authorization. Please note that a restocking fee of 10% applies to all returns. Understanding the complexities of drivetrain diagnostics is exhausting, but before making a purchase, please ensure that the issue with your vehicle is indeed due to the transfer case. If a unit has been mounted in your vehicle, it becomes non-returnable. We encourage you to thoroughly verify the need for a transfer case replacement prior to placing an order. Should you need to initiate a return, reach out to us within 14 days of receipt.
