I have one on my '04, and I really like it. Works well with my new body lift also. I'm almost positive that it will work on the '05-06. There really isn't much too it, just about a 4" piece of frame on each side. The only problem I ran into is that I had to spend an hour opening a hole in the frame with a file and sawzall to get the bolts to fit in. Not that bad though.
