The Black Box Planetary gearbox is a gear reduction unit that fits between your existing transmission and transfer case. The Black Box can be shifted between 1:1 high range for highway duty and a deep 2.72:1 gear reduction when in low range. The Black Box is designed for the 4x4 enthusiast who is seeking significantly more slow speed control than currently available.
