H&R sway bar kits are made of high tensile strength (hf) 50CrV4 steel alloy that produces reduced roll response time and increases cornering stiffness over stock.
Larger diameter, stiffer sway bars increase lateral stability and reduce body roll, which improves cornering grip.
H&R sway bars are cold-formed and heat treated and have 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 adjust roll stiffness.
To finish off these great sway bar kits, they come with new urethane/teflon composite bushings that won't squeak or need lubrication.
The best sway bars, and best sway bar brands for Porsche are available here at MGC.
