so im taking off the rear 56" spring of my 88 3/4 ton sub and its in pretty good condition. and i have a 88 1/2 ton that needs a face lift. im already lifting the 3/4 ton to put some 41" iroks under it. its kinda like my show/fun truck (show because im in high school) hey you gottat pick up country girls some how. right? anyways i have my previous 1/2 ton sub. the running one. that i would like to put new axle shafts in. maybe some 37's and i want to do a cheap suspension lift. so i was thinking i would go ahead and do a spring swap. put the 56" in front. so first question. what do i need? how high will it lift? i have a 56" in the rear already so what how do i lift the rear? and is the flex really that different compared to a standard lift kit? just curious.
