In automotive suspension systems, the anti-roll bar plays a crucial role. It is also known as a sway bar, and is an auxiliary elastic component.

Its primary function is to prevent excessive body roll during cornering, thereby enhancing vehicle stability and comfort. By reducing body roll, the anti-roll bar helps improve the vehicle's handling performance and can enhance ride smoothness.
