I went with 2.5" 1/4" wall square tubing(there's no kill like overkill) Which I don't recommend since most people are lifted this high so 2.5" won't clear. it was easy to do($10 in steel and drilling six holes plus some bedliner). If you go with smaller tubing, you would be advised to find a way to drill/mill some access holes so you can get a socket through. For anyone who hasn't put these on, how much clearance do you have between the bottom of your stops and your axle? What about you Zeus? Mine seems a little on the smallish side( good for articulation, bad for load carrying) so I'd like to know what is the normal clearance(non lifted). Here's what I got:
