He is correct.

It is all about Statics. Look at an I beam What makes it so stiff? When you try to bend it your compressing one side and tensioning the other. Your doing that to the top and bottom sufaces. Now the farther spaced a part they are the better. The web gives them leverage to fight compression / tension. Round 2" tube of the same wall is not as rigid as a square tube. Now go to rectanglar and stand it upright now your really talking. ;)

My bars are 82" long 2" x 3" with 3/16" wall. I do not run a hiem on the axle end. I run a 3/4" heim on the frame end.

Work great.:)

Thanks John. What rod ends are you running in the rears of yours? I have to put new ends on mine and make some new brackets.

A quick question on placement. Anybody have bars on a rclb? 60" would put the front of the bar on the part of the frame that angles up just behind the cab. Would that work or would it be better to make them longer and put them on the flat part of the frame about inline with the door handle?

I have pro comp bars and they seem to work okay, not a lot of hooks on them though...
Does anyone else use these or has used these? Has anyone had any problems with them? Just want to check so I know if I will be looking at this thread in the future to make new ones...;)

I would make them long enough to reach the flat portion of the frame.

The ideal place to put them is where instant center will be. If you have weighed your truck and it shows you the front vs rear weights then take those numbers and divide one by the total weight that will give you a percentage number. You can take that number and measure wheelbase and put the bars at that percentage of wheelbase. That point will be instant center. Thus you will achieve the best lift/load/transfer. If you are running in 4x4 it won't matter as much though.
