Has anyone noticed or does anyone know why the back end of a sportsmans skid plate/chassie angles up slightly?

 

funny you should bring this up, I noticed this same thing on my Hawkeye, it angles up just ahead of the rear dif. at first I thought I had bent the frame but a quick check of other 300/400s confirmed the same bend in the sub frame.
Just a guess, but thinking this bend lines up the suspension geometry of the lower A-frame

 

Has anyone else noticed this besides jokout.
