H&R sway bar kits are made of high tensile strength (hf) 50CrV4 steel alloy that produces reduced feedback response time and increases stiffness over stock. Stiffer bars increase lateral stability and reduce body roll which improves cornering grip. H&R sway bars are cold-formed and heat treated with seamless, no-weld end flanges. Shot-peened for lifetime durability. If it is beneficial to the vehicle, some bar kits have mounting hole options for the end links. To finish off these great sway bar kits, they come with urethane/teflon composite bushings that won't squeak or need lubrication.
