Anti-sway bars, also known as sway bars or stabilizer bars, are an essential component of a vehicle's suspension system. They are designed to limit the lateral movement of the car during cornering, ensuring better handling, and stability on the road. However, sometimes they are referred to as anti-roll bars or roll bars, but they all serve the same purpose. Another synonym for anti-sway bars is torsion bars, which are found on some older model cars. They are named so because they use the torsion effect to counteract the movement of the car when turning. In summary, anti-sway bars, sway bars, stabilizer bars, anti-roll bars, roll bars, and torsion bars all aim to provide a safer and more stable driving experience.
