H&R® Experience the H&R difference today

H&R Sport Sway Bars are crafted from a special (hf) 50CrV4 steel alloy—the highest tensile strength available. The quality of the material and design guarantees smooth transitional sway bar function—decreasing the feedback response time—and increases stiffness over stock. H&R Sport Sway Bars improve a vehicle’s lateral stability and cornering grip, while reducing body roll. H&R Sport Sway Bars are precision engineered—designed and manufactured to be strong, resilient, and durable. Adhering to the same manufacturing philosophy as H&R’s world-renowned springs, H&R Sport Sway Bar design and production receives significant attention to detail and commitment. Each sway bar is cold-formed and heat-treated, with forged seamless bar ends. H&R shot-peens the sway bars to increase durability and check for dimensional correctness. At H&R’s ISO9001 certified manufacturing facility in Germany, production is completed in-house and each sway bar must pass a series of rigorous quality control tests to earn H&R’s approval and yours. Being 100% German made means a commitment to doing it right—giving you the best quality product.

Advantages of H&R sway bars:

  • High-tensile steel
  • Precise forged ends
  • Powder coating
  • Composite rubber bearing
  • Less body roll
  • Higher agility
  • Minimal loss of comfort
  • Developed and made in Germany

Experience cornering in a new way! The multi-hole adjustment of most H&R anti-roll bars allows the desired self-steering behaviour (oversteer/understeer) of the vehicle to be influenced. The result is better handling through, for example, a reduced roll tendency. This way, an individual suspension setup can be achieved, entirely according to personal needs and preferences – and of course with part approval! H&R sport stabilizers can be combined with all H&R suspension products as well as with original or sport suspensions from other manufacturers. In addition, they can be installed on the front axle only or on both axles.
