Trail-Creeper 2.28x4.70 Dual Transfer Cases
Trail Creeper 2.28x4.70 Dual Transfer Cases
If a 4.7:1 transfer case gear ratio has proven insufficient for the type of offroading that you want to do and you look forward to the kind of quality time with your tools that modifying your floorboards and drive shafts would require, it's time to upgrade to a Dual Transfer Case setup.
With a stock 2.28 transfer case, a 3.93 first gear ratio and 3.90 differential, your crawl ratio works out to 35:1. The Trail-Creeper™ 2.28x4.70 Dual Transfer Case changes the crawl ratio in that scenario to 164:1! That massive torque and fine control certainly changes the game, enabling you to take on terrain that others fear to crawl.
The Dual Transfer Case will work in 1979-1995 Toyota Pickups and 1985-1995 4Runners as long as they use one of the transmissions described in the Transmission Matrix below. Note that V6 trucks with the R150F transmission require an adapter plate for compatibility. The G58, A340F and A340H transmissions are not compatible with the Dual Transfer Case!
We manufacture 24 different variations of this magnificent unit. Choosing the right variation for your application requires defining the following four options:
2.28 Gears: [New] or [Remanufactured]
Input Gear: [21-Spline] or [23-Spline] - In the Dual Transfer Case the front reduction box (that connects to the transmission) needs to match the Input Gear of your transmission. V6 and 4-cylinder turbo trucks use a 23-spline input, all others use 21-spline - See the Transmission Matrix below.
Shifter Options: [Top Shift], [Foward Shift 4" Offset] or [Forward Shift 4.5" Offset] - Top shift T-cases have the shifter(s) on top of the transfer case. Forward Shift T-cases have protruding shift forks that attach to shifter(s) mounted on the transmission. In the Dual Transfer Case, the rear reduction box (connected to the front and rear output components) is always Top Shift. The front reduction box (that connects to the transmission) in most cases should match the shifter configuration of the transfer case it replaces. Find your specific transmission in the Transmission Matrix below and look under "Shifter Options" for the specific shifter configuration of the stock transfer case.
Single or Twin Stick: [Single Stick Only] or [Twin Stick Ready (Loose Interlock Pin)] - A twin-stick allows independent control of low/high range and 2WD/4WD engagement. With a twin-stick configuration you can switch between 2WD and 4WD without stopping and access 2WD Low-Range for better handling when traveling between obstacles on a trail. In the Dual Transfer Case, the rear reduction box (connected to the front and rear output components) can be either single or twin stick, based on your personal preference.

|This transmission was originally sandwiched between a 3VZ-E V6 engine and a VF1A chain-drive transfer case. Replacing this transfer case with a Trail-Creeper™ 2.28x4.70 Dual Transfer Case requires our V6 adapter kit (SKU: 100086-1-KIT)
|Forward Shift-4" Offset
- Our Trail-Safe™ T-case Output Seal will be included and installed at no additional cost.
- While these transfer cases ship with a new shifter base, neither the [Single Stick Only] cases nor the [Twin Stick Ready] cases ship with shifters. Shifters must be purchased separately if needed (see "Related Products" below).
- Installation will require significant floorboard and driveline modifications to fit! The front driveline must be lengthened and the rear driveline shortened.
- If you are unsure if you have the 4" or 4.5" Forward Shift
