Benefits of adding a leaf spring?
The Stable Loads are very intriguing as they can be completely disengaged while the truck is empty and engaged only before a load (preparing to tow or carry weight in the bed) is applied. The simplicity of the design is great too.
Check out SuperSprings. These are the ones for a 2018 4x4 F150 they sell them for a RWD as well. So thing is they will raise the rear about 1-1.5 inch and when not having the weight in the back the ride will be stiffer. But they do help prevent rear sag by providing a 1,500 load leveling capacity. Kind of like a rear air bag system, only this will be like if you had the bags full all the time. I sell them for like fleet companies that have the service stuff in the rear and bunch of equipment. Give you a better ride and none or less sag if you keep weight on it all the time. You can get them through your local 4 Wheel Parts store even if they don't show available on the Super Springs site.
