I had 33's and 4" of susp and 1" of body on my TJ and the top of the rack(old straight bar style set for a hardtop) with the kargomaster basket was 7'2". I now have 35'5 and I have the extra inch of height. Don't forget that however tall your rig is, you need to make sure your CB/two-way antenae is an inch or two taller. I could drop the height by an inch or two by setting the bar for a softtop, but I do run the hardtop in the colder months.
