Superior handling without sacrificing ride comfort. Frequency Selective Damping technology for Ford E-350 and E-450 Class C motorhomes. Filters vibrations. Controls pitch and roll. Sold individually.
The first shock absorber that offers superior handling without compromising comfort. If you own a Ford E-350 or E-450 Class C motorhome, you know the challenge of balancing ride comfort with handling control. Factory shocks often leave you choosing between a harsh, controlled ride or a soft, wallowing one.
You can't find a better shock for your Class C motorhome than FSD: KONI Frequency Selective Dampers. KONI has combined the benefits of performance and comfort into one shock absorber, eliminating the compromise. The 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, the 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. Whether you're navigating mountain roads or cruising the interstate, your Class C will handle confidently while passengers enjoy exceptional comfort.
Firm damping for large bumps and corners, soft damping for small bumps and rough roads
Filters out annoying vibrations before they enter the coach for an incredibly smooth ride
Internal construction built for heavy-duty motorhome use and demanding conditions
Reduces body pitch during braking and acceleration, minimizes body roll in corners
Frequency Selective Damping (FSD) is KONI's patented technology that automatically adjusts damping based on the type of road input. How it works: The FSD shock recognizes the difference between high-frequency vibrations (like rough pavement texture) and low-frequency body motions (like body roll in corners or pitching over bumps). It stays soft for the high-frequency inputs to maximize comfort, but instantly firms up for low-frequency motions to maintain control. The benefit: You get the best of both worlds - a plush, comfortable ride over rough roads WITHOUT sacrificing the firm control you need for handling, braking, and cornering. No more choosing between comfort and control - FSD delivers both simultaneously. This is why KONI FSD shocks are the gold standard for Class C motorhomes. They transform the driving experience by eliminating the traditional trade-off between ride quality and handling performance.
