- Each NP263HD unit is fully rebuilt with upgraded internal components to improve durability, longevity, and long-term performance. Our precision remanufacturing process includes the installation of a newly enhanced aluminum rear case half — a critical upgrade that eliminates the common “pump rub” issue known to affect these transfer cases particularly the 263HD over time. This preventative design modification helps protect against oil loss and catastrophic internal failure, ensuring extended service life even under demanding use. We are the most affordable, fully rebuilt option in the United States — offering unmatched quality with absolutely no compromises.
About This Unit
The NP263HD (New Process 263 Heavy Duty) was the OEM transfer case used in 2001–2007 Chevrolet and GMC 2500HD and 3500HD trucks equipped with 4L80E transmissions and 6.0L V8 engines. Identified by the NP1 RPO code, this electric shift transfer case features a durable chain-driven design, a 2.72:1 planetary low-range gear ratio, and magnesium or aluminum housing components depending on the model year. This unit shifts electronically with a push button on the dash.
What distinguishes the 263HD from standard-duty models is its heavy-duty input and output shaft construction and its compatibility with high-output drivetrains. It was engineered to handle towing, off-road, and high-load conditions without failure — making it a staple in GM’s heavy-duty 4×4 lineup.
This transfer case is currently on sale — making now the perfect time to upgrade or replace your OEM unit with a fully remanufactured model built to exceed factory standards.
Note: Before completing your order, please verify that you require the NP263HD model, not the NP263XHD. If you’re running a 6.6L Duramax or 8.1L engine with an Allison transmission, you may need the NP263XHD Transfer Case — the extra heavy-duty version built for high torque GM applications.

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.
Please note that return shipping costs will be the responsibility of the buyer.
