I'm running a body lift and leveling kit with no issues. It is also way less expensive and invasive on a truck than most suspension lifts if you're only looking to get 3.5" - 4" of lift. That being said, you're going to have issues with the width of the tires you're looking at with anything less than 5" of lift. You may be able to trim your way out of it, but there's no way to tell for sure until you put them on. If you decide to put a suspension lift then I would recommend the Zone 4.5" or Rough Country 5" knuckle lift. The BDS, Fabtech, and McGaughy kits are all great kits if you're planning to do extreme offroading, if not; then you're wasting money.
