Built to perform

H&R manufactures its swaybars from high strength spring steel, formed in a single piece for maximum integrity, then cold worked and heat treated for durability. The result is a robust roll control upgrade that resists twist and maintains geometry under load, helping your tyres stay in their optimal contact patch.
