As you have made modification to your Ford Mustang, F150, or Focus, there is a strong possibility that you need to consider installing a Roush sway bar as well. Any modification that you have made to your vehicle that alters the way that it handles through added horsepower of suspension upgrades can put added stress on your automobile. A performance sway bar is able to help take on that added stress. It is the sway bar that stabilizes the chassis against front end roll and sway when you are cornering. It works by using the upward force that is placed on the outer wheel during a turn to lift the inner wheel. This situation reduces the unevenness of your vehicle. A performance sway bar is extremely durable. It will last you year after year for mile after mile regardless of the kind of driving that you do. This durability also means that your sway bar will not bend, flex, or crack under the stress and pressure that is created on your vehicle when you are cornering. The end links of a Roush sway bar are made of urethane so that your handling will not be too stiff. Roush has been known for crating quality parts ever since 1995. A Roush sway bar is no exception.
