Koni 93-10 Freightliner XC Rigid Rear Axle

The first shock absorber that offers superior handling without compromising comfort. You can´t find a better shock for your motorhome than FSD: Koni frequency selective dampers. We have combined the benefits of performance and comfort into one shock absorber. FSD is firm for control over large bumps and corners, but soft for comfort over expansion joints and rough roads. While Koni is known to reduce bouncing in motorhomes, our FSD shocks include a special valve that filters out annoying vibrations before they enter the coach. The result is an incredibly smooth ride, with plenty of shock left to control pitching and swaying.
