KONI Special Active shock absorbers revolutionize the driving experience with their cutting-edge technology, the FSD valve patented by KONI.

Previously, shock absorbers always involved a compromise between comfort and handling, with comfort prioritized for everyday driving and better handling required for more demanding driving conditions, such as on a track. No conventional shock absorber could offer both, until KONI created FSD (Frequency Selective Damping) technology. 

Our engineers have put all their expertise into it. The FSD valve makes the KONI Special Active shock absorber high-performing, comfortable, and uncompromising in both handling and comfort. 

FSD technology is a valve added under the piston in a KONI shock absorber. This valve operates based on the piston rod's movement frequency, without electronics. It releases oil flow to lower pressures within the shock absorbers, thus improving ride comfort. The shock absorber automatically adjusts to adapt to road conditions. This advanced technology has been proven on over 10 million vehicles as original equipment. 

Koni offers the Special Active for a wide variety of applications, from buses and cars to SUVs, motorhomes, and vans. The FSD valve provides an additional advantage for a specific application. 

If you own a convertible, roadster, or other open-top vehicle, you may have experienced "hood shake." This occurs when the dashboard vibrates due to road imperfections. A lack of chassis rigidity in a convertible is often the cause. 

The Special Active's FSD technology helps minimize hood vibrations. These shock absorbers completely transform the driving experience, making it comfortable without compromise.

Therefore, the FSD valve is perfectly suited to all types of vehicles. If you are looking for optimal comfort without compromising on handling, the FSD valve is for you!
