leveled or not leveled. Leveled you will be too big to fit in most garages at a little over 6'8. Not leveled you might be just a little below that. I have the same issue right now since i work at hospitals and most have garages. I can fit leveled now stock tires and leveling kit under a 6'8 garage and have about 1 1/2-2 inches to spare.
