Our sway bar experience has been opposite of Salvo's observation.
That's not an observation but fact! The suspension consists of springs and dampers. Do not confuse the two. They have completely different rolls in a suspension system. Rocking is due to inadequate damping. A sway bar is a torsion spring. It's not a damper.
If you enter a driveway or a speed bump at an angle the sway bar will become energized. The bigger the bar the more energy the bar attains and the more rocking you'll get.
