Trail-Creeper 4.7 Transfer Case with 23-Spline Input Forward Shift 4.5-Inch Offset,Loose Interlock Pin Trail Gear

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 inch Offset or Forward Shift 4.5 inch 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).
