Adapters & Spacers

When installing a new part in your vehicle, it’s safest and most effective to make sure that everything fits in properly. With Atlas adapters and spacers from Advance Adapters, you can make slight adjustments to your parts to alleviate any potential fitment issues and variations in output shafts such as diameter or length.

These high-quality adapters are designed to fit precisely with your components and keep them in place effectively while using the stock build of your vehicle while upgrading to aftermarket drivetrain components. Adapters are a must when a replacement Atlas transfer case has different inputs or outputs than the OEM case — or they are drastically different in size and shape. They’re made of heavy-duty lightweight aluminum and precision-machined in-house for an exact fit.

Transfer Case Adapters & Adapter Spacers

Find the adapters and spacers perfect for your Atlas transfer cases so that you can install new parts safely and effectively. Use Atlas adapter kits to link a case with all sorts of popular off-road transmissions both stock and aftermarket. We’ve developed transfer case adapters for the TH400, TH350/700R, 4L60E, Jeep JL 850RE, 6R80 and many other models, mating components effortlessly while keeping them as close as possible to the factory location.

Individual adapters and spacers are also available for custom layouts. Rotation ring spacers come in thicknesses from half an inch to almost two inches depending on the alignment needed. Some connect to the transmission while others link the tail housing — whatever is going to produce the most reliable, least disruptive configuration.

No matter your vehicle, you’ll find what you need here — and you can search based on your current transfer case and/or transmission using the filters.
