Trac bars or ladder racks (for those of us that are old school) keep the axle pinion from twisting upwards. It is not perfect but it keeps the proper angles for the universals for leaf spring suspension. It eliminates leaf spring torque which gets rid of or reduces the rear wheel hop. We could dial in a dragster by lengthening or shortening a rod to make it track strait down the track and not pulling to one side or the other.
