Koni’s new Frequency Selective Dampening (FSD) shock is the latest technology from the shock company’s line-up of high performance shocks and struts. Unlike a conventional shock, Koni FSDs can dynamically change the shock valving, depending on the frequency of the impact and its severity. The compromise between comfort and handling is nearly gone.
In addition to the standard valving on the shock, a parallel valve can open and close in response to suspension movement. This additional valve provides the needed adjustment to keep the suspension soft on uneven road surfaces and firm on even road surfaces. No cables, wires, or valves to turn, FSDs adjust as needed. FSDs are sold in sets of four in order to keep the vehicle’s shock balance even front to rear.
Combine with ipd safety anti-sway bars and you have the perfect balance between comfort and superior road holding.
