Sway Bars & Links
Sway Bars and Links
Sway bars and their links control body roll when cornering. A sway bar is a tubular metal rod of spring steel that is designed to twist. It is usually mounted to the vehicle body using D bushes. The sway bar links are on each end of this rod and connected to the left and right hand suspension arms. As a car turns into a corner and the body leans the bar twists and fights the body roll.
Sway bars have different thicknesses and are rated in 'hard' and 'soft' A harder bar restricts body roll (Stiffer, greater twist resistance) where a softer bar allows more body roll. (Softer, less twist resistance.) Adjustable sway bars will allow the links to be moved to make the sway bar stiffer or softer. Sway bars play an important role in suspension tuning.
