Stabilizer links are known by a variety of names: anti-sway bar, sway bar, stabilizer bar, anti-roll bar, and roll bar. As these various names suggest, the part is meant to add stability by keeping the vehicle from rolling excessively during turns or on bumpy roads. The stabilizer arms connect wheels together through a series of short arms connected by a torsion spring. They are attached to the chassis with flexible bushings. The stabilizer keeps the wheels at the same height or distance from the chassis, reducing the feeling of roll inside the vehicle. In addition to helping correct body lean of the car, the stabilizer also helps improve handling; adjusting it can correct both oversteering and understeering.
