Has anyone put a leveling kit (spacers) on top of there lift kits on an 05-07 F250 4x4. I have a 8" Rough country lift and im wanting to put a 2.5" Leveling kit on top of it because the back is higher than the front right now. But all the shops are telling me they wont do it because it already has a lift and it will wear all my front end components out. I have an adjustable trac bar so that wont be a problem. So has anyone had any problems with there leveling kits ontop of there lifts?
