I'm looking at getting the 5-6" Kelderman lift kit for the front and rear of my 04. 5. I want to run bigger tires than 35's so that rules out the KORE system. I lifted my F250 PSD and it rode like a roller skate from then on. Not going there again. Really like the improved ride and all from the Kelderman. Anyone have the system? Anyone rode in a truck or have personal experience?? Thanks
