I was gonna say that, but I was out painting the frame on a rig and didn’t get back in time. I looked at all the steel thickness charts and concluded it was likely 13 gauge. Apparently it’s being advertised as 10 gauge. The Crown replacement is apparently 18 gauge. Who knows unless you put a caliper on it at the mounting flange. All that matters in the end is that the stock GTS on 03-06 TJ’s is substantial enough to withstand good hits for most daily driver/off-road warrior types.
