front dual rate…

I’m no engineer in the suspension dept. but im surprised none of the suspension experts have tried to make a budget dual rate kit for the front end of these that would utilize the stock springs, (yes I know changing all of the springs give you the best overall outcome) but the front springs on these are more of an area for improvement than the rear, I look at the front and I see 5+ inches of threads, just waiting for another spring to be installed, my buddies are all on a tight budget and not one of them would spend 750 on a full spring kit, but if there was a way to improve the front for lets say 100-150 bucks they would be all over that, maybe its not possible or flat out doesn’t work with the stock springs but everytime I look at the front springs/shocks I see wasted potential.
