A 4 x 4 is a great vehicle to have. Their rugged drive trains will allow you to drive through just about anything. Snow, mud, rocks, your 4 x 4 will go through it all. However, for most people, the bulk of the time, they will not need the off road capabilities of their truck. While you are driving around on dry roads, if can be very helpful to be able to switch from four wheel drive to two wheel drive. Four wheel drive puts more wear and tear on your engine, drive train, and tires, and it takes a lot of power. If you can switch to two wheel drive, you can save wear and tear on those components, increase your power, and improve your fuel economy. If you vehicle does not have the capabilities to switch between drives, then the Superwinch Locking Hub is the right accessory for you. The Superwinch Locking Hub is basically a knob that mounts inside the hub, and a simple quarter turn will change the mode of your vehicle. You can drive to the trails with two wheel drive, turn the knob, and switch right into full 4 x 4 capabilities once you reach the trailhead. The Superwinch Locking Hub is a great product made by a company that has an understanding of hubs. Gearhead hobbyists certainly deserve great sales help while looking at reliable parts for a car or truck.
