never seen a frame under the axle though that is my thing.. I mean i guess it would make it easier to drag frame though. just trying to figure out why the axle is over the frame.thanks for posting that too
its done to keep the frame out of the interior. of course your lift is limited because the frame is in the way but the taller wheel you run, the more lift you can get. heres another one thats been done for awhile..
