ABOUT Bilstein Corp of America®

When August Bilstein laid the foundations for the innovation incubator BILSTEIN in Altenvoerde in Germany's Westphalia region in 1873, nobody had any idea of the crucial influence the company's products would one day have on the driving comfort and safety of cars.Now, the name BILSTEIN has for many decades been closely associated with high tech in the field of suspension design, driving comfort and safety. In order to expand this position in the future, BILSTEIN became a division of ThyssenKrupp Technologies AG in 1988, and a wholly-owned subsidiary in 2005.
