I have a 01 f150 supercrew, its 2wd. I currently have a fabtech 7.5" lift with 2" lift spacers and out back I have 5" superlift leaf springs with 3 added leafs from my stock pack.
my plan is: BTF mid travel suspension (I have it (arms, lift spindle, tierods) just need my brake rotors, bumpstops then I can start to install it, I will need to determine the amount of travel, just before the uniballs bottom to figure out my amount of travel I will have. then I will weld on the bumpstop mounts and get limiting straps to keep it from killing the uniballs. depending on how I want it to sit (has 3" lift spindles) I can have it sit lower by putting in stock springs, or sit higher by putting in lift springs.. I can expect 13-14" of front travel. out back I will be using my lowering shackles and remove leafs from the pack to get it to sit level.. with the leafs being regular lift leafs (not deavers or nationals) they wont sag as much over time, however my ride will be a little bit stiffer...but I tow and put heavy stuff in the bed so I need the payload.I can expect ~16" of travel.
