Screw numbers.
My 2" x .25 DOM lowers, all 4, look like bananas.
My 1.5" x .25 tie rod looks like a banana.
But I guess the little hex stock will be OK, as long your link mounts are below the axle centerline. Mine aren't, which is probably a contributing factor.
Are you still going on about that post 5 days ago? You know that from below center line of the axle to above does make a difference. Thats simple physics.

1.25 hex: .23438
1.25 x .75: .1666
1.5 x 1.0: .26542
1.75 x 1.25: .3885
2.0 x 1.5 (synergry): .53594
2" solid (rock Krawler) .784
not too bad. I dont know If your working on different #s or what..
Now lets talk about. Yield strength. People dont want their arms looking like bananas right?
1018, what MOST companies use
http://www.pmtsco.com/1018CD.HTM
tensile strength, 64000 PSI. Yield strength, 54000 PSI
12L14, What I use
http://www.pmtsco.com/12L14CD.HTMtensile strength, 78000 PSI. Yield strength, 60,000 PSI
Back where I used to work as an engineer we would use 1-1/4 hex for gear shafts. They dont come perfectly strait of course like anything. We would take the 4 foot long shafts under our 4 ton press to straiten them to tolerance. In order to take a .003 bow out of this material you would have to bend it atleast 8 inches in the opposite direction.
So are you saying I am completely wrong on my math and material choice?
