If you’re in the market for a reliable transfer case, let me tell you about the remanufactured options from Zumbrota Drivetrain. These guys have been in the game long enough to know what works and what doesn’t. As vehicles evolve and get more complicated, they’ve adapted their processes to keep up, and that’s something you can trust when you’re looking to upgrade or replace your transfer case.

Each transfer case is remanufactured with a keen eye for detail. They don’t just slap things together and call it a day. There are three quality inspections throughout the process, so you can be sure you’re getting a solid build. First, they do a pre-inspection to catch any cracks or wear that could cause issues down the line. Then, during the remanufacturing, they check that all the parts meet OEM specs. Finally, there’s a thorough post-build inspection to ensure everything is up to their high standards. It’s like having a safety net for your vehicle.

One of the standout features is the hydro blasting and rinsing process they use to clean the cases. It really brings them back to an OEM-like finish, and once you see it, you’ll understand why that matters. Plus, they replace all the common wear components—seals, bearings, viscous couplers—so you know you’re getting a fresh start. They even pack these units in high-density plastic totes to prevent any damage during shipping. It’s all about making sure you get what you pay for.

Now, let’s talk specifics. This transfer case assembly is designed to fit models like the 1998-1989 Chevrolet Blazer and the 1988-1989 GMC Jimmy, and it’s compatible with the 700R4 transmission. You’re looking at a NV241G manual shift with a 27 spline input and a right-hand front output shaft. It’s got a 2-inch speedometer hole and a 4-inch square front output yoke—pretty standard stuff that makes installation a breeze.

And just to give you peace of mind, all these transfer cases come with a standard 2-year, unlimited mileage warranty. So whether you’re reselling or installing it in your own ride, you can feel confident knowing you’ve got a dependable product. If you’re serious about keeping your vehicle running smoothly, this is definitely worth considering.
