Anti-Roll Bar


The Anti-Roll Bar, also known as sway bar or stabilizer bar, helps control body roll when cornering or driving on rough or uneven surfaces. It usually connects between the two lower control arms. When the vehicle moves around a curve, the body leans outward. It causes the lower-control arms to move in opposite directions, twisting the sway bar. However, the sway bar resists being twisted, which stiffens the suspension during turns so less lean out or body roll results. Anti-Roll Bar action may also occur if one tire hits a bump or pothole while the other does not.
