Anti-roll bars, also known as sway bars, are components in a vehicle's suspension system designed to reduce body roll during cornering. They connect the left and right wheels, helping to distribute weight evenly and maintain stability. This enhances handling and improves the overall driving experience, especially in turns. When a vehicle turns, the anti-roll bar resists the lateral forces that cause the body to lean. By doing so, it helps keep the tires in better contact with the road, improving traction and safety. Anti-roll bars are commonly found in various vehicles, from sports cars to SUVs, and are essential for performance and comfort.
