So, you’re in the market for a transfer case? Let me tell you about the Zumbrota transfer case—this isn’t just any old part; it’s a solid piece of craftsmanship that’s been rebuilt to last. With a robust 2-year unlimited mileage warranty, you can hit the trails or the daily grind with confidence, knowing you’ve got a reliable component under your rig.

What sets Zumbrota apart? Well, they’ve got over 150 years of combined experience in their corner. Each transfer case is meticulously restored to like-new condition. They don’t just slap it together and call it a day; every unit goes through a rigorous inspection process. They check for cracks, stripped threads, warped shafts, and all that jazz. If something’s worn out, it gets replaced—bearings, seals, viscous couplers, you name it.

One of the coolest features is their hydro-blasting and sandblasting process. This isn’t just about cleaning; it’s about restoring that OEM finish. They really take care of the internals, too, with a proprietary deep cleaning that gets rid of any grime that might slow you down. And before it leaves the shop, each unit is spin-tested to ensure it shifts smoothly and operates quietly. You really can feel the difference when you’re behind the wheel.

Shipping is another area where Zumbrota shines. They pack these transfer cases in high-density plastic totes, so you won’t have to worry about any damage during transit. It’s all about getting you the part in perfect condition.
