Here’s what you get with the Klune-V Extreme Underdrive. The basic coffee-can–sized unit has the shift pod attached and is ready to bolt in. The output spud shaft is available in different spline counts for many different applications, and the input spline arrangement has just as many options. Two adapter mount plates and a cable shifter complete the package—all for around $1,895. Try to get lower transfer case gears and axle gears for that small chunk of change. Plus, you now have options available for gearing selections.
