When exploring our range of shock absorbers, you'll notice numbers like 1S, 2S, and 7S in the Vigor part number. These aren't just numbers; they're your key to a perfect ride! Each number represents a different type of shock absorber, designed to meet various driving needs and preferences.

  1. 3S - Magneto-rheological (MR) Dampers: These advanced shock absorbers use a magnetorheological fluid, which changes viscosity in response to magnetic fields. This allows for real-time adjustment of the damping level, providing a dynamic and responsive ride quality. Ideal for high-performance and luxury vehicles where adaptability and comfort are paramount.

  2. 2S - CDC (Continuous Damping Control) Non-Adjustable Shock Absorbers without Active Control: These dampers offer continuous damping control but lack active electronic control systems. They automatically adjust the damping force based on road conditions and driving dynamics, offering a balance of comfort and stability.

  3. 7S - Adjustable Controlled Active Dampers: These are high-end shock absorbers with active control systems. They use sensors and electronic controls to adapt the damping force in real-time, offering the ultimate in ride comfort and handling performance. Suitable for premium vehicles where maximum control and adaptability are desired.

  4. 1S Non-Electric Variants: a purely mechanical system without any electrical components or coil-based mechanisms

Important note: Certain shocks are specifically designed for particular car models or types. It's important to match the shock absorber to the vehicle's specifications.


We are actively engaged in the development and enhancement of our entire range of shock absorbers. Please note that not all types of shocks may be available at this moment.
