If you're looking to do some serious off-roading, then you're going to need a set of traction bars. Traction bars are designed to keep your wheels from slipping and losing traction when you're driving on rough or slippery terrain. They work by connecting the axle to the frame of the vehicle, which prevents the wheels from moving independently of the body. This helps to distribute weight evenly and keeps the tires from spinning out. While they're not required for every off-road adventure, they can be a lifesaver when conditions are less than ideal. So if you're planning on doing some serious 4x4ing, make sure you've got a set of traction bars in your arsenal.
