What is the function of a stabilizer bar?

[NoahRose]

The function of a stabilizer bar: When the horizontal heights of the left and right wheels are different, to prevent the torsion of the bar body, the stabilizer bar generates anti-roll resistance to inhibit body roll. When the suspensions on both sides move up and down synchronously, the stabilizer bar does not function. It only comes into play when the suspensions on both sides move asynchronously due to road undulations or cornering. When both wheels pass over the same road bump or pothole, the stabilizer bar does not function. However, if the left and right wheels pass over different road bumps or potholes, meaning the horizontal heights of the left and right wheels are different, it will cause torsion of the bar body, generating anti-roll resistance (Roll Resistance) to inhibit body roll.
