You can't really tell from the picture, but it has triangulated supports underneath in the far back so it's actually over twice as thick back there in the middle. Should be the same thickness, the dg is .25 aluminum stock also. Always good to guard the linkage, had a small scrape on that before I got the skid.
I just saw them at rocky for 70 or 80 for the bullet series, make sure it is indeed the bullet series, big difference. That's probably the cheapest place, the company that makes them is based out of Utah, and so is rocky.
