Toyota Truck Dual Transfer Case Kits

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.
