Meet the Zumbrota NP273 Transfer Case

If you’re looking for a solid remanufactured transfer case, you’ve stumbled upon a gem. Zumbrota Drivetrain has been in the game long enough to know what works and what doesn’t. We’ve refined our processes over the years, adapting to the complexities of modern vehicles without losing sight of what matters: quality and reliability.

When you choose our NP273, you’re not just getting a part; you’re getting peace of mind. Each transfer case goes through a rigorous three-step inspection process. First, we check for any cracks or wear that could cause headaches down the line. Then, during the remanufacturing, we make sure every component meets the original equipment manufacturer (OEM) specs. Finally, we do a post-build inspection to ensure everything is built to our high standards. You can trust that this thing is ready to hit the road.

What Makes It Stand Out?

• We clean each case using a hydro blasting process that restores it to an OEM finish. Seriously, once you see it, you’ll understand the difference.
• All seals, bearings, and viscous couplers (where applicable) are replaced—no shortcuts here.
• We ship these bad boys in high-density plastic totes to prevent any damage during transit. Your transfer case arrives ready to install.
• And just to sweeten the deal, we back it with a 2-year unlimited mileage warranty. Drive with confidence!
