Sway Bars

The fitting of bigger Whiteline sway bars is still the best dollar for dollar handling improvement you can make, as cornering loads are spread more evenly across the tires to deliver more grip and improved tire wear! Whiteline adjustable sway bars allow their stiffness to be altered by increasing or reducing 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. Whiteline adjustable sway bars offer from 2 up to 4 points of adjustment allowing in some cases 10 distinct stiffness settings for precise handling bias adjustment.
