I would never drive it around that low. I wanted mine to sit like that and after calibrating the ride height to sit nice and low, I took it for a spin and realized I destroyed the handling of the truck.

If you want it to sit like that buy coilovers, because in your picture you are probably an inch from the bump stops, if that.
