I see sites offer for a 7.5" or 7.6" IFS... which does our truck have? I have a 2007 z71 4wd... also, do I need "thick" gears or just the regular gears? cant seem to find ANY info on the front throughout these threads... thanks for the help

Fronts a 7.6. Same as the h3. Rear is aam 8.0. You don't have to use thick cut gears.
