Q: What is KONI Frequency Selective Damping (FSD)?
A: FSD technology automatically adjusts shock damping based on road frequency, providing firm suspension control during heavy inputs while softening over expansion joints and rough pavement.

Q: Will KONI shocks improve the ride of a Chevrolet Express motorhome?
A: Yes. KONI FSD shocks significantly improve ride comfort and stability by reducing suspension bounce, harsh impacts, and rear suspension movement common on heavily loaded van and motorhome chassis.
