Info: Anti Roll bar - AKA Sway bar

Anti Roll bar - AKA Sway bar

A bar conecting both front and both rear wheels to try to prevent body roll.

Advantage - increases the suspension's roll stiffness -- its resistance to roll in turns, independent of its spring rate in the vertical direction.

Disadvantages - Because an anti-roll bar connects wheels on the opposite sides of the vehicle together, the bar will transmit the force of one-wheel bumps to the opposite wheel. On rough or broken pavement, anti-roll bars can produce jarring, side-to-side body motions (a "waddling" sensation), which increase in severity with the diameter and stiffness of the anti roll bars.
