Since our inception over 40 years ago, Bilstein has been a unique and driving force in the automotive suspension industry. Bilstein was first to apply the patented gas pressure principle to controlling ride characteristics on automobiles and introduced the world's first monotube gas pressure shock absorber. Today, Bilstein continues to be the leader in the development of gas pressure shock absorber technology. No other shock manufacturer has been able to equal the performance and enhanced ride characteristics of Bilstein. The Bilstein name graces not only monotube gas pressure shock absorbers, but also single and twin tube Macpherson strut style suspensions. From racing and testing in Formula 1, NASCAR, SCCA, Rally, and Off Road to original equipment on BMW, Ferrari, Jaguar, MercedesBenz, Porsche, Subaru, Toyota, GM, Ford, and Chrysler vehicles, Bilstein Gas Pressure Shock Absorbers have proven to be the best.
