Toyota Dual Case Adapter Kits

Installing a dual transfer case adapter in your Toyota will give you more ways to experience the outdoor lifestyle. These special adapters are also known as doublers because they add a second set of low-range gears to the existing range, giving you twice as many choices. If you enjoy all kinds of off-roading, regularly tow on hilly roads or need precision gearing for dune bashing and rock crawling, an Advance Adapters Toyota dual case conversion package will provide this flexibility.

Components for Toyota Dual Cases

Creating a transfer case doubler involves attaching a second reduction unit to your existing case. We have quality conversions products for Toyota trucks and 4 Runner vehicles to give them two times the gearing — and two times the adventure. Shop reduction housings, crawler double bearing adapters and couplers that work with common OEM and aftermarket Toyota transfer cases. This includes t-case components for 21-, 23- and 26-spline setups. You also can order a complete Toyota Hi-Lux Transfer Case Rebuild Kit, which was one of the first cases that had replicable low-range reduction. You’ll be able to restore this classic transfer case and enjoy double or even triple the low gears for years to come.

If you have questions about which transfer cases can be doubled and how to do so, use our contact form to get in touch. Since 1971, Advance Adapters has been designing the best dual transfer case systems and backing them with in-depth knowledge. All dual T-case adapter kits are engineered and manufactured in the U.S.
