All of our Staged Motor/Gearbox kits are sold as matched pairs, meaning the price you see is for one complete vehicle. Kits fit all Power Wheels Porsche GT3's and Power Wheels C7 Corvette Stingrays. If you have a 6V Corvette you will need to get the 6V to 12V+ Conversion Kit linked below, along with the appropriate battery upgrade kit.
We highly recommend a Brake Reduction Module with all Staged kits to increase gear longevity, unless your vehicle has an aftermarket electronic speed controller.
