Most shock absorbers are designed to offer a firmer ride OR to maximize ride comfort. And complete computerized systems can deliver both comfort and performance, but at too high a price for the average consumer's vehicle.
The KONI FSD (Frequency Selective Damping) shock combines excellent road holding and handing characteristics with no-compromise comfort levels. It's a two-in-one solution from KONI that doesn't require the installation of sophisticated electronics, cables or sensors. Firmness for sporty driving on even road surfaces. Smoothness for a comfortable ride on uneven road surfaces.
It's possible via KONI's patented Frequency Selective Damping technology - technology that actively controls the damping level on the basis of the vehicle's body and suspension movement frequency. FSD shocks are a smart suspension system that adjusts automatically and in a fraction of a second to road conditions and driving style.
