Big false claim that traction bars don't help a mopar . They don't do as much front to back due to none center mounting in our leaf springs . But they for sure help with side to side movement. A piñon snub also does nothing for side to side movement or keeping both sides of the car down .
This guy explains it better than I could but they do help , they will improve your hook up and side to side twisting.
My dad always said the same thing he ran his challenger with them and not with them many times over years. He take them off when mopar guys told him he didn't need them and then go back & forth & xousi see in all his vhs videos that the car did much better with them
