Pedders Lancer/Forester/Impreza/Legacy Adjustable Endlink Kit (Various Model Years) PED-424476

A sway bar is essentially a torsion bar which is mounted laterally on the vehicle and is designed to reduce side sway. The sway bar attempts to accomplish this by transferring movement from one side of the suspension to the other. This is done through the connection of a torsion bar to each side of an axle by flexible links, which are called Sway Bar Links.
