About This Unit
The BW4473, was the OEM full-time AWD transfer case found in GM’s 1500/2500 van lineup from 2003 to 2014. It was used in both the Chevrolet Express and GMC Savana AWD platforms and is easily identified by RPO code NP3. This chain-driven, single-speed transfer case distributes torque through an internal viscous clutch pack, allowing continuous AWD operation without user input or electronic engagement.
Built with a lightweight cast aluminum housing and a wide 1.25-inch chain, the BW4473 is optimized for durability while keeping weight in check — ideal for commercial-duty and fleet van applications operating in all-weather environments.
This 44-73 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.
- If you need any help confirming vehicle fitment, please do not hesitate to contact us at 888-926-3583 to ensure we are providing you with the correct unit.
Don’t settle for cheap AWD replacements. Here’s why fleet owners and shops choose Transfer Case World for the BW4473.

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.
