FSD Shock Kit

FSD is the abbreviation of Frequency Selective Damping. It is the latest technology of Koni, specifically designed to combine the ultimate in comfort and road-holding. This no-compromise shock absorber was launched to the world in 2005. A revolutionary new technique which combines the benefits of firm and comfortable suspension in a single perfect shock absorber. Firm for sporty driving on even road surfaces. Comfortable for a smooth ride on uneven road surfaces.

If you are able to change the damping force level in relation to the frequency of the movement of the vehicle, you create the possibility to solve the conflict in terms of comfort and handling ever present in conventional dampers.

The Koni FSD technology does just that! In effect giving you Active Ride Control. The groundbreaking FSD technology has been designed and patented by Koni to end the compromise between comfort and road-holding. This new feature can be used as an integrated part of the hydraulic valving system inside the damper.

Consequently, no additional cables, sensors, or any other electronic devices are needed to operate this system. It operates fully hydraulic and frequency selective and is therefore an economical and effective solution to improving a cars handling. It will give Ride and Handling Engineers a constructive, additional variable in fine-tuning the cars behavior.


  • Excellent ride quality on all road surfaces
  • Available for most newer cars more coming
  • Gold metallic finish shocks
  • Less expensive than electronic systems
  • Lifetime Warranty

I haven't received my parts yet, but they just notified me that the order has been shipped. I think this is very fast service. Their online ordering system was very easy to use. And best of all, they had the lowest prices on the items I ordered. Even the shipping charge was less than some other companies. So far, I am very satisfied with Autoplicity, and I will certainly check their Website the next time I'm looking for parts.
Product as described. Customer Service very helpful. Will shop again.
Autoplicity had an item my vendor had on backorder for weeks in stock and shipped it very quickly. I'm glad i found this place on the web, and will be looking forward to doing business with them in the future!
Ordered on a Friday and they had it shipped by Monday and will be at my door step by Wednesday. Prices are amazing I will have to buy from them again.
