In general, the Fox 2.0s aren't harsh at their fill ride height/out of the box ride height. That being said, if you want the softest ride possible with this kit, you feasibly could lower their ride heights down to a 0" factory height and use a leveling spacer of some sort so that you take preload off the spring while still getting a gain in height. However, 2.0s do tend to be a hint stiffer than stock, though we contend that it's not necessarily a bad thing which how much body roll and wallowing these trucks tend to do.
