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 Power Wheels Mustang models.

We highly recommend a Brake Reduction Module with all Staged kits to increase gear longevity, unless your vehicle has an aftermarket electronic speed controller.
