Spring rates
ive got an 86' F150 that is mostly stock right now, its got 6" lift and 38's on it. but once i get out of Iraq, i will be doing some major work on it. and the only problem im having right now is what kind of spring rates im going to be using for my front/rear 4-link set-ups. im hoping someone can guide me to some specs or provide some tips on how to approach this situation. thanks for your time.
