Well, kinda sorta......Heavy duty suspensions were options on most models. The higher horsepower cars came stock with heavier bars, but, other models could have them too. Go by the number on the end of the bar. What are the numbers on your existing bars? Thicker bars can have a dramatic effect with improved handling, especially with a front sway bar. It also effects the ride comfort for some people, so, that will be a matter of personal choice as to how thick a bar would be best for you. Cruise ship or skateboard, the choice is yours! :lol:
