Do a quick search around here. My '05 did not have the bolts, and I had to get them when I lifted it. If you look @ the rear of your lower control arm, you should see a bolt head and a washer that will have markings (like tick marks) if you do have the adjustable cams. It should be plain if you do not have the adjustable ones.
It depends on the born-on-date of your truck. I'm not sure of the exact dates, but a quick search should find them for you.
