Original-Equipment. The world’s foremost automotive brands put their confidence in Bilstein quality. Why? Because brand develops and series-produce suspension components in collaboration with Bilstein partners from the automotive industry. By placing your trust in Bilstein experience too, you’ll be opting for the BILSTEIN driving experience when you exchange your suspension components.
Gas Pressure Technology. Over time, the mono-tube gas pressure technology developed by BILSTEIN has established itself as a standard in automotive construction. This technology involves keeping the oil in the absorber under pressure, which prevents it from foaming when temperatures and loads are increasing. As a result, full damping power is retained even when the system is placed under extreme stress, a feature that can be observed in the self-lowering piston.
Mono-tube Upside-Down Technology. The original and best: The original mono-tube gas pressure shock absorbers bore the BILSTEIN name, and we’re still responsible for producing the best there is. BILSTEIN’s mono-tube technology is the number-one choice in motorsports and series-production sports cars: no other type gives engineers the same freedom to choose the perfect installation location or position (e.g. Upside-Down technology).
Twin-tube Technology. The proven technology of a twin-tube absorber is applied in the vast majority of all vehicles. BILSTEIN‘s twin-tube absorbers, featuring “original equipment manufacturer” quality that has undergone rigorous testing, offer a marked improvement in driving characteristics with universal spare parts replaced in a timely and efficient manner.
In 1954, Bilstein® was the first to realize the potential offered by an idea of Prof. Bourcier de Carbon, a French researcher in the field of vibrations. The aim was to eliminate the physical disadvantages of the conventional telescopic shock absorbers, whilst at the same time making the dampers lighter and able to be fitted in any position. 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. The partnership and co-operation within the group will enable the company to continue to inspire with innovations in the traditional Bilstein way.
