When one side of the car starts to dip, the sway bar (connected to the other side) acts to pull it back up. The primary function of anti-roll bars is to reduce body roll by adding to the roll resistance of the springs. The outer ends of the anti roll bar attach to the unspring part of the suspension. A conventional anti-roll bar can be incorporated between the trailing arms to increase the body roll stiffness of the suspension or alternatively built-in anti-roll rubber blocks can be adopted (Fig. This job requires that both … The anti roll bar is secured to the front subframe using bushes and a u shaped clamp.
