I've got a 2011 2wd XLT SUPERCREW w/ 6.5 ft bed aka Project Family Hauler. It's a street truck that sees occasional towing and fire roads. I have my jeep for any harder wheeling. I'm looking at running a 4 in spindle, coilovers and new upper control arms up front for a 6 in lift. Out back I'm debating between running a 5 in block, using a 2 in billet block with Sky jacker FR904s 4 in springs, or saving to have Atlas or Alca to make me a leaf pack for 6 in of lift. I'm debating between Halo and fox coilovers. Also debating on which control arms to use. I called skyjacker about their leaf springs being listed for a 4wd and not a 2wd, aren't 2wd and 4wd leaf packs interchangable? Any input is appreciated
