I bought my Rough Country 4" lift a couple months ago. Of course everyone told me how horrible they are and you may remember my post about the height not looking right. Turns out the height wasn't correct. I measured from ground to rocker and came up with 20" (2" shy of a 4"). Called them up, they asked for pics, I sent them and they sent me new springs. Great customer service. Can't wait to get the new ones in and see what 4" is really like.
