ive been thinking about lifting up my truck some how ever since i got it. i recently replaced all my shocks with ranchos that are good up to a 1.5 in lift. one of my questions is if i put in a 3 in body lift would i have to get new shocks? im debating between getting a leveling coils that i found from rough country http://www.roughcountry.com/ford_2wd_83-97_midsize_leveling.html. if i wanted to raise the rear i would throw in some lift blocks. which of these is easiest to do? also how would a 1.5 in lift kit impact my mileage since mine is terrible. and how would a 3 in body lift impact my mileage? i would be doingn this mainly for looks since my truck is 2wd and any offroading i would do would be light trial rides. thanks for any help.
