Koni FSD (Frequency Selective Damping) set for B5.5 chassis Passat FWD, including TDI and 1.8T. Koni's FSD patented technology provides a firm ride on long bumps and corners for control, and a soft ride on expansion joints and rough roads for comfort.
The FSD has an extra valve that controls an oil flow parallel to the piston assembly that opens over high frequency inputs, such as expansion joints, providing a smooth ride. The valve closes over low frequency inputs such as cornering transitions, providing better control. The valving is integrated into the strut, is non-electronic, and does not require any external sensors or adjustments.
We strongly recommend replacing all strut and shock mounts when installing a new suspension. Worn front strut mounts can negatively affect alignment, steering handling as well degrade ride quality. Worn rear mounts can cause knocking/rattling noises as the shock is no longer held securely in a worn mount. (Available as an option below)
Get front or rear mounts for half price when selecting them as options below.
