There are a few things to consider when setting up a traction bar. The first is how much weight the vehicle will be carrying. This will help determine the amount of tension that needs to be applied to the bar. The next thing to consider is where the bar will be attached. It is important to make sure that the bar is securely attached so that it does not come loose while driving. Finally, you need to decide how long the bar should be. This will depend on the size of the vehicle and how much space you have available.
