I had great results from my Koni FSD shocks. My previous Monroe, and most other shocks, are gas charged which means they are under "compression" when just sitting still and they transfer even the slightest road joint bump in to the chassis.
The Koni FSD shocks are NOT gas charged so they dampen all of the many small bumps that you may receive on an interstate as well as doing a great job of dampening the large bumps. Not being gas charged also means that they are an easy install. I think you will be happy with your results.
