(To clarify, I saw your Facebook post with additional under-carriage shots) It’s clean, for sure, but with cost cutting comes sacrifices. With the extensions being welded directly to the frame with no additional reinforcement plates (like the competitors you mentioned have), that’s a ton (or more specifically, four tons) of downward stress being put onto those welds in the event of a hard downward impact. That’s a lot. And if they fail, they’re going to rip quite violently out of the frame. The clamp on style is much stronger, evening the stress of flexing across the entire height of the frame instead of just on one 2” square. I’m not saying these WILL fail because obviously they’re custom and not a lot of data to go off of. Just in my personal opinion I don’t think they look as strong as a frame-mounted clamp on style with reinforcement plates, and I’d want as much strength as possible.
