Every spring produced by H&R comes from the H&R ISO 9001 certified engineering and manufacturing facility in Germany. All H&R springs are produced from a special 54SiCr6 spring steel, which has strength rated at 290,000 psi resulting in unrivaled tensile strength and resiliency. Combining high-quality materials with advanced designed tools and techniques makes the final H&R product lighter and more durable than other automotive coil springs. At H&R product design and development is of the highest importance. All H&R springs are “cold” wound on specially designed CNC machinery and then time-tempered to re-align the molecular structure of the steel to ensure quality and durability. All springs are shot-peened to increase the service life of each spring by more than 200%. Each spring is then sent through the H&R exclusive “SuperBlok™” system, which cycles each spring to ensure that sagging will never occur. Lastly, the H&R special powder coating process coats each spring with a flexible and durable finish that is highly resistant to corrosion, chips, and scratches. At H&R we care about quality –– the whole production process, from start to finish, is done in-house to ensure the most consistent, highest quality product possible.
