Stabilizer bar belongs to the car's suspension system. Anti-sway bar or anti-roll bar is its second name. Its function is to keep the car's body steady while in a sharp turn. While in a turn the car is forced to put more weight on the outside tires and less weight on the inside tires due to centrifugal effect. Negative influence on steering is obvious under the case. What we really want to do is to remain the car's weight staying distributed evenly on all four tires. A stabilizer bar exists for this demand. It works by moving force from one side of the car's body to another to keep it flat. When the car mounted with stabilizer goes into a turn, the front suspension member of the outside of the turn gets pushed upward. The arm of the sway bar gets pushed upward, and this applies torsion to the rod. The torsion moves the arm at the other end of the rod, and this causes the suspension on the other side of the car to compress as well. The car's body tends to stay flat in the turn.
