Monotube Technology - the Number-One Choice in Motorsports

This photo dramatically illustrates the size difference between the larger working piston inside a Bilstein monotube shock and smaller one found in a typical twin tube shock.The original and best mono-tube gas pressure shock absorbers all wear the Bilstein name, because Bilstein shock absorbers are the best there is. The number-one choice in motor-sports and for series-production sports cars, the monotube shock absorber has a unique design that affords the freedom to choose the ideal installation position or location.

  • Monotube shocks feature a large surface on the working piston which increases the damping power and provides better handling.
  • The design of the monotube shock improves the dissipation of heat which improves the life of the shock and enables a consistent and dependable level of absorber performance.
  • Bilstein's Upside-Down Technology creates a safer functioning shock absorber.

Twin-tube Technology - Quality Proven Under Rigorous Testing

This photo illustrates the size of the working piston inside a Bilstein twin-tube shock absorber. The twin-tube shock absorber is time tested and are used in most vehicles. Bilstein‘s twin-tube absorbers are “original equipment manufacturer” quality and have undergone extensive testing. These Bilstein twin-tube shocks offer a noticeable improvement over standard twin-tube shock absorbers. They can be installed quickly and easily.

  • Twin-tube shocks employ oil or gas pressure technology.
  • All twin-tube shock absorbers are OEM quality and rigorously tested.
  • Twin-tube shocks are more affordably priced than mono-tube shocks, while still providing a high level of performance.

Gas Pressure Technology - Full Damping Power Under Extreme Stress

This photo illustrates how gas pressure keeps the shock's oil from overheatingBilstein's gas pressure technology has become an established standard in the automotive industry. By employing a chamber of high pressure gas to keep the oil in the absorber under pressure, Bilstein's Gas Pressure Technology prevents the shock from becoming over-heated. Over-heating can cause the oil within the shock to begin foaming. Because this technology prevents over-heating, Bilstein shock absorbers provide full damping power even when the shocks are placed under extreme stress. This feature is most evident in the self-lowering piston.

  • The gas pressure technology allows for a faster responding piston which allows for a higher level of traction and more precise handling.
  • With improved traction and handling comes a safer driving experience.
  • Ideal in performance and sport suspensions.
