Yes, you can convert a 4x4 vehicle. If you want to use the stock transmission, you will need to shop Legacy EV’s list of stock transmission adaptor plates. If you want to get rid of your transmission you can mate directly to the transfer case or mate to the transfer case using a gear reduction box, provided your transfer case is divorced. If your transfer case is not divorced, a custom adapter plate will likely need to be manufactured. It is also possible to mount a motor to drive the front axles, and another motor to drive the rear axle.
