Pretty easy - get the 2" Teraflex coil spacers for the front and a set of OEM Dodge Ram rear shackles. That will get you close to 2".
Those spacers are about $50 for the set and you can get 2 JY shackles for about $10. Otherwise Teraflex does the full set (2 spacers, 2 shackles) on their website for about $160.
