2018 Isata 3 FW suspension upgrade
I know there have been many threads on this topic but thought I would add my experience. After 3 years and 20,000 mile my oem suspension was worn out. The rig would wobble or oscillate side-to-side throwing everything around the RV every time we went over a bump. When we hit a pothole on the freeway it felt like the rv was sitting directly on top of the axel and was very jarring to the riders.
I had Sumo springs added to front and rear as well as Koni shocks front and rear. Total cost with material, labor and alignment was over $2,000. So far the investment has been worth it. The Koni shocks are self adjusting and provide strength on recoil so they really help to stop the side-to-side movement. The sumo springs keep some separation between axel and frame reducing the jarring. The overall ride and handling is much smoother to me.
This is a very subjective topic and each person likes a different type of ride and handling. However, just wanted to share my own experience and say it makes my Isata 3 much more enjoyable to drive and ride in.
Next problem to solve is the clunking sounds from the Helwig Swap bar...
