An anti-roll bars or sway bars help reduce the body roll of your vehicle during cornering and turns without lowering or affecting ride quality. They can can be installed in the front and rear of the vehicle and often adjustable. Depending on the application, the purpose of a sway bar can vary, although not all vehicles are equipped with an anti-roll bar. Race cars may opt for a stiffer sway bar. At HKP Tuning we offer many variations for most applications by companies like H&R Springs, Eibach, aFe Power and Whiteline.
