Check out Thuren fabrication coils. Cheaper solution than carlie and in my opinion just as good. I have them on my 16 3/4 diesel. I put them on right away to level the truck. They are a 2.5 or 3” easy ride coil. I didn’t upgrade to the good shocks just the thuren branded ones. Better than stock but my back end is still really stiff and makes washboard no fun. Helped front end a lot. I am sure the fox or other shocks offered would help even more.
