These are a very stout design!!! The welds are very nice and the craftsmanship is above all. Am extremely impressed with these. These weigh in at about 90lbs for the pair! Did i mention these are stout! 3/16" Steel plate entirely. From my searching these give the most coverage for protection to the underside of the tub. They catch the mid and rear body mounts and would not be too difficult to add a 3rd mount up front, which is what i am doing. Am placing the new front mount where a front cage hoop will tie into the floor thusly tying the hoop into the frame. This is capable due to the excellent amount of underside area of protection these offer. Which is one of the main reasons i went with t and t's rails.
