If you’re in the market for a transfer case that won’t let you down, you might want to check out what Zumbrota has to offer. These guys really know their stuff. Each transfer case is rebuilt to a level that’s hard to beat, thanks to a crew with over 150 years of combined experience. That means you’re not just getting a part; you’re getting something that’s been thoroughly inspected and tested to ensure it’s ready to hit the road—or trail—without any hiccups.

Here’s the deal: Zumbrota doesn’t just slap a new coat of paint on old parts. They take the time to check for cracks, stripped threads, and any wear on the gears. Every single unit goes through a rigorous process that includes replacing all the bearings, seals, and viscous couplers where needed. And they don’t stop there. They use a unique hydro-blast rinse and sandblasting method to clean both the inside and outside of the cases, bringing them back to an OEM finish. It’s a level of care that shows in the end product.

Oh, and you won’t have to worry about noise or shifting issues—each unit is spin tested to ensure everything operates smoothly. Plus, they ship these bad boys in high-density plastic totes, so they arrive at your door in one piece, ready to install.

Features:

• Quality inspections at every stage of the remanufacturing process, so you know you’re getting something solid.
• A state-of-the-art hydro blasting and rinsing process that restores the cases to that fresh-out-of-the-factory look.
• Every unit comes with 100% replacement of seals, bearings, and other common wear components, so you can hit the ground running.
• Shipped in sturdy plastic totes to prevent any damage during transit—no surprises when you open the box.

Fitment:

• Jeep Cherokee: 1987-1990
• Jeep Comanche: 1987-1990
• Jeep Wagoneer: 1987-1990
