Koni® 8805-1020 - 8805 FSD Front Driver or Passenger Side Non-Adjustable Shock Absorber

Two characteristics that seemed diametrically- opposed, proved to be a source of inspiration for specialists from KONI. Following lengthy development and testing, the ultimate solution was reached: KONI FSD - Frequency Selective Damping. A revolutionary new technique whereby the benefits of both types of ride characteristics are combined in one perfect shock absorber. Banishing the disadvantages of the past. FSD shock absorbers; a smart suspension system adjusting automatically to road conditions as well as driving style. And all of this in a fraction of a second. FSD guarantees greater stability, greater control and thus greater driving pleasure. To learn more about how FSD works, click here. KONI reconfirms with the FSD innovation a leading position as innovative supplier of high-quality shock absorber products.

Vehicle damping has always been a compromise between comfort and road-holding. An obvious example is a Formula 1 racing car which offers the best possible road-holding but with minimal comfort. In a personal of sport car one expects to experience the ultimate in comfort, combined with safe road-holding. Minimum damping is required for your comfort whilst strong damping is needed for safe and stable driving. This conflict of goals can not be solved with conventional front and rear dampers.

KONl shock absorbers with Frequency Selective Damping (FSD) technology, have been specifically designed for personal and sport cars and they combine the ultimate in comfort and road-holding. The purely mechanical solution and thus the independence of electronic control components are the basis for the the first choice of KONl FSD High Performance Damper if you have to solve the familiar everlasting problem.

In standard shock absorbers the main damping characteristic is defined by the oil flow (I) going through the piston assembly. Combining it with the FSD feature, KONl added a special valve which is able to control a parallel oil flow next to the one going through the piston. This parallel oil flow (II) is closed by the FSD feature, giving a rise in damping force almost linear to the time that the piston is moving in one direction. Put simply: the FSD feature is a hydraulic amplifier that delays the build up of pressure. One could say that an extra tuning option has been created in order to get the best possible combination of handling and comfort. Since it is an integrated part of the hydraulic valve system inside the damper, no additional cables, sensors or any other electronic devices are needed to operate an FSD damper. FSD is the simplest and most economic way to significantly improve the ride and driving characteristics of every car. Certainly in comparison with costly systems which work on the basis of computer technology, complex electronics and sensors.
