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 modern Jeep Wrangler models using 10" tires like the common B7659-2459 tire.
We highly recommend a Brake Reduction Module with all Staged kits to increase gear longevity, unless your vehicle has an aftermarket electronic speed controller.
