What is the main purpose of a sway bar in a vehicle's suspension system?

The main purpose of a sway bar, also known as an anti-roll bar, in a vehicle's suspension system is to reduce body roll during turns. When a vehicle corners, centrifugal force can cause the body to lean toward the outside of the turn. The sway bar connects the left and right sides of the suspension, helping to distribute the load more evenly between the two sides. This reduces the amount of tilt or roll that occurs, which enhances stability and control, allowing for better handling during turns. By minimizing body roll, the sway bar helps maintain tire contact with the road, improving overall vehicle performance and safety during cornering maneuvers.
