1. These three anti-sway bars all fit the 1973 style K-frame in our Valiant. The factory bar at the top doesn’t have enough roll resistance for the cornering speeds that this car is capable of. The black bar in the middle worked fine but it weighs 14 pounds. The tubular Hellwig bar at the bottom of the picture only weighs eight pounds. Six pounds might not sound like a substantial weight savings, but when added with all of the other weight shaving, it adds up.
