When it comes to transfer cases, Zumbrota's got your back. These aren’t just any rebuilt units; they’re crafted with care by folks who really know their stuff—over 150 years of combined experience, to be exact. So, when you install one of these bad boys, you're not just swapping out a part; you’re getting a piece of mind with a solid 2-year, unlimited mileage warranty. That’s right, drive it as much as you want, and we’ve got you covered.

What sets Zumbrota apart? For starters, every transfer case goes through a rigorous inspection process. They check for everything from cracks and stripped threads to gear wear and chain stretch. If it doesn’t meet the high standards, it doesn’t make the cut. Each unit gets a full rebuild, meaning all bearings, seals, and viscous couplers are swapped out for fresh ones. You won’t have to worry about wear and tear here.

Cleaning is a big deal too. Zumbrota uses a unique hydro-blast rinse and sandblasting technique to make sure both the internal and external parts come back looking sharp—like OEM quality sharp. After that, they go through a proprietary deep cleaning process that leaves no room for dirt or grime. And don’t forget about the spin test! Each finished unit is spun up to ensure it shifts smoothly and runs quietly.

Shipping is a breeze, too. These transfer cases come packed in high-density plastic totes, so you can be sure they’ll arrive in one piece—no more worrying about damage during transit.
