Don't be so negative speaking facts about knowing the height limitations before buying or lifting a truck.I hope the OP figured out what to do since last year.....
Lesson, measure where you park if that is important before you lift. I measured the opening at the garage at work since there is no street parking even before I ordered the Ram. I knew I would lift it and researched the height. Perfect.
Three months later they put in a height limit bar and a roll up flood gate at 6'3". I was pissed. They put a key fob reader outside the exit that was still high enough so I could get in lol.
And didn't even notice this thread was a year old.
