I have designed and built my own skids as well as fabricated them for others in the Tacoma community. I had both steel and aluminum on my rig over the years, I do 3/16 steel or 1/4 aluminum. I’ve bent and scratched both to hell and back.
IMO- aluminum is super gummy over rocks, it gouges more than steel, more resistance, and deeper cuts. But it is lighter. I know people that use 1/4 steel, seems a bit overkill but I have had to take off 3/16 skids and hammer them back to shape.
Currently I have the 1/8” wall steel ARB full skids on my GX, came with them, I’ve had them on the rocks once, it took more abuse than I expected. I will be building some 3/16 skids soon, to make me feel better on the trail. I will be sure to design an oil filter door and jackpoint!
Some images for reference of my aluminum plate after a nice run in the rocks.
