Our ICON spring pack will offer the ability to be configured to 3 different rates that will be further defined later this week. The spring pack will have a "heavy duty" configuration available (all parts will be provided when purchasing the ICON spring pack to do this).
What I mentioned in that post is that our trailer is equipped with load leveling assist bars. This is a system where you attach bars from both sides of a special hitch and run back to the side v rails of the trailer with heavy tension to help remove load off the back of the truck. This would be the only thing I could think of that would be beneficial outside the kit if you are towing a heavy bumper pull trailer.
