KONI has introduced its new Frequency Selective Damping (FSD) shock absorber at an international press event held at Zandvoort race track in Holland on April 4th-5th 2005. According to the company, the FSD is the first shock absorber to provide superior road-holding without compromising comfort.
KONI FSD addresses the trade-off in conventional suspension systems whereby a soft suspension is associated with poor steering response, excessive pitch and roll, and problems dealing with speed bumps; while firm suspension can lead to a harsh ride and reduced grip on poor road surfaces.
In standard shock absorbers, the main damping characteristic is defined by the oil flow going through the piston assembly. In the patented FSD system, KONI has added a special valve which controls an oil flow parallel to the one going through the piston. The FSD feature closes this parallel oil flow, 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. It could also be described as an extra tuning option, created 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 electronics are needed to operate an FSD damper.
According to KONI, FSD is the simplest, most economical way to significantly improve the ride and driving characteristics of every car. FSD provides a smart suspension system which adjusts automatically to road conditions as well as driving style.
KONI is a leading supplier to automotive OEMs and the after market. Part of ITT Industries, it develops, manufactures and sells high quality, high performance shock absorbers for all kinds of private and commercial vehicles, including buses, trucks, trailers, railway rolling stock and racing cars.
KONI's FSD shocks are in stock and available now!
