What is the function of a car sway bar?

[KinsleyRose]

Balance bars can reduce the body roll of a car during fast cornering, thereby improving the car's cornering speed. Essentially, a sway bar functions as a torsion spring. It connects the left and right shock absorbers of the car, helping to suppress the rebound and compression of the shock absorbers during cornering, which in turn reduces the extent of body roll. Below are some key points about sway bars: 1. Prevalence: Most cars are equipped with sway bars on the front suspension, and some performance-oriented vehicles may also have them on the rear suspension. 2. Function: Sway bars enhance handling performance, but they can negatively impact ride comfort. 3. Adjustment requirements: Sway bars may require adjustment, especially if the suspension has been modified. After modifying the suspension, the wheel alignment data of the car will change, necessitating an adjustment of the sway bar.
