The anti roll bar is a rigid steel bar which functions structurally to prevent the chassis of the car from leaning and rolling too much when taking a turn or rounding a corner.
The anti roll bar is positioned below the car body and attaches to the right and left hand wheel suspension with anti roll bar or drop links. Most cars have a front anti-roll bar which links the two front wheels and some cars have an anti roll bar which sits at the back of the car and connects the two rear wheels.
The anti roll bar keeps the wheels in alignment when the car turns a corner, reducing the body roll of the whole suspension which improves the overall handling of the vehicle.
The anti roll bar itself doesn't wear but it can break or suffer damage in an accident. Over time the drop links, which link the anti roll bar with the rest of the car's suspension, will wear down, however, which can affect the handling and suspension. If the anti roll bar has been damaged in a collision, or you are fitting an anti roll bar into your car for the first time, it's important to install a part that's compatible with the make and model of your vehicle. Purchasing a anti roll bar will ensure you get the ideal part.
