Its all 1/4" steel. They are huge, and heavy, and hopefully they'll stand up to anything I throw at them. They hang down 3" lower than the t-case skidplate.
There is no way to mount them even an inch higher because of the transmission crossmember, and even if I cut that out and built a new one I'd only be able to tuck them up another 1", maybe 2" if I got really creative. But then I'm messing with the structural integrity of the frame. . and since I already know I'm cutting out the front crossmember, i didn't feel like going there. Like i said before. . if I don't like how low they sit I'll just have to fab up something similar to Josh's with shorter control arms.
