i have 3 inch body lift, add a leaf and f150 coil spacers... i suggest if you dont go suspension lift all the way is to go 3 inch body lift, add a leaf, shackles, and the 2 inch lift coil spacer. you should be able to run 33x12.50 on a 15x8 inch rim if you dont get swampers. stick to an all terrain or mud terrain, NOT A SWAMPER. just a little bit of info from experience
