Transfer Case Adapter Kits

Transfer Case Adapter Kits

Update or upgrade your vehicle with a transfer case adapter kit from Advance Adapters. Transmissions and transfer cases are typically designed so they only fit in the combination that arrived from the factory. If you want to swap components, you will likely need a transfer case adapter to connect them and ensure proper power transfer. Common reasons for an adapter include switching from a manual to an automatic transmission or getting an aftermarket transfer case.

Our selection of transmission-to-transfer case adapters includes designs and sizes to accommodate all popular 4x4 makes and models. From Dodges and Jeeps to Fords and Toyotas, there are plenty of vehicle parts included. We also have adapter kits that fit the top transmission and transfer case manufacturers, including New Process, Asin, Dana Spicer, Borg Warner and our in-house Atlas transfer cases. With our helpful product filters, you can easily locate the correct adapter kit. Learn more about what makes Advance Adapters the best choice for all your aftermarket product needs.

Affordable Transfer Case Adapters

If you love your vehicle but it has recently started to display some transmission issues, or you're looking for an upgrade to do more extreme towing and off-roading, we have options to suit your application. With the right parts, you can simply upgrade your transmission and get it running like new (or better). Upgrading your transmission is a major project, however, so it's critical to get the correct parts for your needs.

The components in each kit help to ensure that the parts from each vehicle fit together seamlessly. Options like an NV4500 to NP205 adapter kit, for example, can be used to install a new, stouter transmission. We can set you up with a T56 transfer case adapter, a Toyota dual-case adapter, a 4L60E transmission transfer case adapter and hundreds of other solutions. You will receive all necessary parts and hardware made of premium materials. Select a kit to view detailed information on fitment along with tips such as how to identify the transfer case and whether you need to relocate any components.
