Zumbrota Drivetrain RTC4479G-2 Transfer Case for 2011 Cadillac STS 3.6L AWD - RTC4479G-2

So, you’re thinking about a Zumbrota transfer case? Let me tell you, you’re making a solid choice. These bad boys are rebuilt with a level of care that’s hard to find these days. With a two-year, unlimited mileage warranty backing you up, it’s like having a safety net while you hit the trails or cruise down the highway.

What really sets Zumbrota apart is the craftsmanship. We’re talking over 150 years of combined experience here. Each unit is meticulously restored to like-new condition. They inspect every nook and cranny for wear and tear—things like cracks, stripped threads, and gear wear. If it’s not up to snuff, it gets replaced. Every single bearing, seal, and viscous coupler gets swapped out, ensuring you’re not just putting a band-aid on an old part.

And let’s talk cleaning. Zumbrota uses a unique hydro-blast rinse and sandblasting process that brings everything back to that fresh-from-the-factory look. After that, they go through a shot-enticed deep cleaning that leaves no room for dirt or grime. Plus, before it leaves the shop, each transfer case is spin-tested to make sure it shifts smoothly and quietly. You really can’t beat that level of detail.

When your transfer case arrives, it’s packed in a sturdy high-density plastic tote. No more worrying about it getting banged up during shipping. You want it to arrive in perfect shape, and Zumbrota makes sure it does.

Features:

  • Each unit goes through a thorough quality inspection during the remanufacturing process.
  • Cleaned using advanced hydro blasting techniques to get that OEM finish back.
  • 100% replacement of seals, bearings, and viscous couplers—no shortcuts here.
  • Shipped in durable plastic totes to prevent any transit damage.

Fitment:

  • Cadillac STS Base 2011

Specifically, this fits the Cadillac STS 3.6L AWD from 2011, with part number RTC4479G-2 Zumbrota BW4479 Transfer Case. If you’re looking for reliability and performance, this is a solid upgrade for your ride.

The shipping fee quoted in the shopping cart includes transportation of the product to your location as well as the return of your core to the manufacturer. If you opt to send your core in advance, we offer a 50% refund on the shipping cost. However, please note that this option may prolong the overall process, so we generally advise against it.
