Faith, I would love to install a set here, but ain't got the funds right now to add them on my truck, but the Super Springs are deffinately my choice for what i use the truck for. Now Run-it is a great source for the SuperSprings as he also has experience setting up suspension for road course cars and uses his truck daily.

The Sulastic's, by what i have seen on thier site, add a joint to the leaf springs set-up allowing for more flex and absortion, now this would most likely work great under normal driving and not carrying much, but since the design of the leaf spring is to hold weight, if you add a flex point when weight is added it will tend to sag. THis is my opinion and just using some logic, obviously the suspensions on performance cars are completely different, but watching their video, that shackle moves really easy I wonder how it would look like under a full load or towing a trailer.
