Fox did not redesign their 2.0s for the 2015-2018 F150s. Your choice of coilover/leveled strut assembly is really going to depend on what kin of ride height you're hoping to achieve. Keep in mind that bot the Fox 2.0s and Rancho QuickLifts can only add up to 2" of ride height and won't get you to 100% dead-level. For a dead-level stance, you'll need to be at 2.5" of leveling. If you're fine with 2", and you don't use your truck off-road, then either the Ranchos or Bilstein 5100s would likely be the better bang-for-your-buck choices.
