If you're in the market for a remanufactured transfer case that won’t let you down, you might want to check out what Zumbrota Drivetrain has to offer. They’ve been in the game for a while, and they know their stuff. As vehicles get more complicated, they've stepped up their manufacturing processes to keep pace. That’s something you can count on when you’re looking for quality and reliability.

Now, let’s talk about the transfer cases themselves. Each unit goes through a rigorous remanufacturing process, ensuring that it meets strict specs. You can feel confident whether you’re installing it in your ride or reselling it. Here’s what makes these transfer cases stand out:

• They’re inspected three times during the reman process—no cutting corners here.
• A pre-inspection checks for cracks and wear that can cause headaches down the line.
• During the reman, they ensure all parts meet OEM standards, so you know you’re getting a solid product.
• Finally, there’s a post-build inspection to make sure everything is up to snuff.
• Each case is hydro blasted and rinsed to bring it back to that OEM finish. Seriously, once you see it, you’ll get why it matters.
• They replace seals, bearings, and viscous couplers where needed—basically, all the stuff that tends to wear out.
• Your transfer case arrives in a high-density plastic tote, so it won’t get banged up during shipping.
• And to top it off, you get a 2-year unlimited mileage warranty. That’s peace of mind right there.
