Trail-Creeper 4.7 Transfer Cases
Trail Creeper™ 4.7 Single Transfer Cases
If you have a 4-cylinder 1979-1995 Toyota Pickup or a 4 cylinder 1985-1995 4Runner, as long as the truck didn't have Automatic Differential Disconnect (ADD), the stock transfer case in the vehicle was a gear-driven RF1A with a 2.28:1 low range gear ratio.
It doesn't take long to realize that a 2.28:1 low range is too high for some terrain. More than twice the torque at half the speed can be achieved with 4.7:1 gear set in your transfer case.
While you could remove your T-case, drag it to the workbench and replace the 2.28 gears with 4.7 gears yourself, spend more time on the trail by simply replacing your stock RF1A with our fully-built Trail-Creeper™ 4.7 Transfer Case.
Additionally, as shown in the Transmission Matrix below, our Trail-Creeper™ 4.7 Single Transfer Case can replace the VF1A chain-drive transfer case in a V6 Pickup or 4Runner when installed with the V6 Adapter Kit (SKU: 100086-1-KIT).
We manufacture 12 different variations of this transfer case. Choosing the right variation for your application requires defining the following three options:
Input Gear: [21-Spline or 23-Spline]
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.
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.
The transmission matrix below will assist you in determining which input gear and shifter options are compatible with your transmission. It is up to you whether you opt for a single or twin-stick configuration to control your transfer case (as long as you don't have a W56-C, D or E transmission that REQUIRES Single Stick).
|year(s)||transmission(s)||input gear||shifter Options||special notes|
|8/83-88||G52/G54||21-Spline||Forward Shift-4.5" Offset|
|86-87||R151F||23-Spline||Forward Shift-4.5" Offset||Bench Seat Models|
|86-87||R151F||23-Spline||Top Shift||Bucket Seat Models|
|88-95||R150F||23-Spline||Top Shift||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™ 4.7 Single Transfer Case requires our V6 adapter kit (SKU: 100086-1-KIT)|
|89-95||W56-C/D/E||21-Spline||Forward Shift-4" Offset||Single Stick ONLY!|
If your adventures lead you to places where even a 4.7:1 transfer case gear ratio is insufficient, you can combine this case with our Trail-Creeper™ 2.28 Crawl Box to create a dual transfer case.
- Our Trail-Safe™ T-case Output Seal will be included and installed at no additional cost.
- If you are unsure if you have the 4" or 4.5" Forward Shift transfer case, please refer to the comparison image at the top of the page.
- 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).
