All of our Staged Motor/Gearbox kits are sold as matched pairs, meaning the price you see is for one complete vehicle. These kits work with all Jeep Hurricanes, Dune Racers, Stingers, and Baja Extremes. Does not work with the 6v Lil Dune Racer.
We highly recommend a Brake Reduction Module with all Staged kits to increase gear longevity, unless your vehicle has an aftermarket electronic speed controller.
