You can get them from Ford for about $100 each. Suggest going up one to two spring rates higher than what you have currently. Ford coils are soft to begin with. On my F250 I went from 5,200LB front coils to 7,000LB coils, which are from an F550.Looking for somewhere to get replacement front coil springs for an 04 F350 2WD supercab.Mine are sagging with 118000 miles.I would rather not use spacers to lift it up to where it was originally.Thanks
