Yes, unless you want the rear higher than stock (when it was new).
Or you could get a mild (2") lift suspension from Old Man Emu and the truck will sit a little higher than stock, and ride and handle better than it did new.
I'm refering to a complete suspension lift, F+R.
You'd fix the rear end sag and gain 2", plus 2" in the front.
The OME (not OEM) lifts are the best there is for ride and handling.
