If you’re in the market for a solid rear differential, you’ve probably come across a lot of options. But let me tell you, Zumbrota Drivetrain has been in the game for over 30 years, and they really know their stuff. I’ve been using their parts for a while now, and I can honestly say that their commitment to quality is impressive. They’ve built a reputation for providing everything from new and remanufactured manual transmissions to transfer cases and differentials. Whether you’re working on a passenger car, SUV, or light-duty truck, they’ve got you covered.

Now, when it comes to rear differentials, it’s easy for companies to make big claims. But Zumbrota doesn’t just talk the talk; they walk the walk. They’ve been specializing in rear differentials for nearly three decades, and it shows. Unlike some places that might cut corners or rely on flashy marketing gimmicks, Zumbrota focuses on delivering a product that you can truly rely on. Their offerings are extensive, catering to everything from everyday passenger vehicles to off-highway vehicles, race cars, and even those heavy-duty pulling trucks. If it’s got wheels, they likely have the parts you need.

For those of you with a Ram 2500 or 3500, you’ll want to check out their rear differential assemblies. They fit perfectly in 2013-2017 Ram 2500s and 2013-2018 Ram 3500s. Specifically, I’ve used the RTC4447D-4 model, which is designed for the BW4447 transfer case without the Aisin transmission. It’s a reliable piece of engineering that makes a noticeable difference in performance, especially if you’re pushing your truck to its limits.

In short, if you want a rear differential that won’t let you down, give Zumbrota Drivetrain a look. They’ve got the experience and the know-how to back up their products, and I can vouch for their quality from personal experience.
