ST anti-sway bars work by connecting the opposite wheels of a car using a steel torsion spring to increase stiffness and reduce body roll. All ST anti-sway bars are manufactured from high quality spring steel and finished with a final powder coating for a great shine and corrosion resistance. Once fitted, ST anti-sway bars greatly improve road handling during rapid load changes and hard cornering by reducing the load difference between the inside and outside wheels. The steering behavior is a lot more direct allowing a sportier and more agile driving style. ST suspension anti-sway bars have been developed through years of experience in the U.S market and now are available for a wide range of vehicles. These sway bars are a perfect compliment to other suspension upgrades such as coilovers or lowering springs. Kits come complete with fresh urethane bushings and can be installed with hand tools. Product images may very slightly from the actual sway bar kit you receive.
