I have the tow mode button and hitch. Also states the autoleveling. But no where on my window sticker did it have a tow package listed or the rear gearing.
checked nissan's website and there is a tow package for the 08 armada; you may have to go to the dealer and see if they still have the 07 brochure. it appears the tow/haul button is standard on all models but the tow package upgrades to hd battery, lower final gear, hitch and harness, and auto-leveling on the SE (AL is standard on the LE). i'm gonna say no unless you can figure out if you have the hd battery and find a label that specifies the lower gear.
