If you wish to go after market - a set of DR front coil overs on a 2005 have thicker stronger springs than the 05 factory front setup and level out a 05 nicely. Call Greg at PRG - he will set you up with a pair. I have been very happy with my set and a pair of Billstein / PRG back shocks for over 2 years now. Rides like a different truck with the suspension changes and looks better as well in my own humble opinion.
