Torsion Bars |
A Torsion Bar is attached to the vehicle chassis. Vertical motion of the wheel causes the bar to rotate along its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length and diameter. Worn torsion bars can cause excessive front tire wear, popping or creaking in the front end, extra play in the tracking system, and pose a serious safety concern. |
