step 1: determine your bolt pattern
Notice that you have the option to select the bolt pattern for the "Lid" and the "Base" of the Eco-Crawler. The Lid refers to your transmission and the Base refers to your transfer case. Yes - you don't have to use your stock transfer case!

VF1, VF2, and VF4 refer to the bolt pattern between the output of the transmission and the input of the transfer case. Over the years, Toyota has modified and updated this pattern, making specific models and generations require different patterns for the EcoCrawler. Refer to the Eco-Crawler Fitment Chart to find what pattern your vehicle uses.
step 2: determine your shifter interface
There are two parts to this: the style of your transfer case shift block (Spade Type or Ball Type) and the position it sits in (Top Shift or Forward Shift).
ball type
If your transfer case shift stick looks like the above photo, your interface is a "Ball Type".
spade type
If your transfer case shift stick looks like the above photo, your interface is a "Spade Type".

If you are using a NWF Trident Shifter Kit, you will want your shifter interface to be "Spade Type"
If your shift rails extend outside of your transfer case, your vehicle is a "Forward Shift". If your shift rails are inside your transfer case, your vehicle is a "Top Shift". If your vehicle is an electric shift, you will want a "Top Shift".

WHAT YOU NEED TO KNOW
- You will need to find a donor manual shift transfer case, or an electric shift and purchase our additional parts kit.
- Torsen transfer cases do not work as donor cases.
- You will need to shorten your rear drive shaft and lengthen your front driveshaft by roughly 6.50" (exact length in product card).
