<P> An anti-roll bar ( roll bar , anti-sway bar , sway bar , stabilizer bar ) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities . It connects opposite ( left / right ) wheels together through short lever arms linked by a torsion spring . A sway bar increases the suspension 's roll stiffness -- its resistance to roll in turns , independent of its spring rate in the vertical direction . The first stabilizer bar patent was awarded to Canadian inventor Stephen Coleman of Fredericton , New Brunswick on April 22 , 1919 . </P>
