This Whiteline 22mm 3 point adjustable Rear Sway Bar offers more grip, better handling and outright performance. Dollar for dollar, it's the best improvement you can make to your vehicle. This adjustable sway bar allows its rate to be altered by increasing or decreasing the length of the lever arms. This permits the roll stiffness to be tuned for different situations without replacing the entire bar. The stiffer the bar, the more force required to move the left and right wheels relative to each other. This increases the amount of force required to make the body roll.
