Hello. I have a 2004 GMC Sierra 1500 Z-71, 4wd. I would like to install a suspension lift, but I need to be able to fit in a parking ramp at work. I am looking at the 4" Rancho kit, which says you can use 33X12.50 tires. Does anyone have this combination and know what the total height of their truck is? I am not positive, but factory height seems to be a little over 6'.
If you dont have this particular combo, I would appreciate any feedback telling me what lift/tire combo you do have and what the overall height of your truck is. Pics would be awesome if you have one handy. Thanks everyone in advance.

 

I am also looking to lift my 2006 GMC Sierra 4x4, dont want to much looking around 4 inches. Has anyone done this with there IFS and have they had any problems, so many choices of which everone seems to be the best, any help or suggestions would be greatly appreciated.
