A quick torsion bar question with pic

[Tom]

Hey guys. We just got a 2010 2500HD 4x4 WT trim truck in at work. I had no idea you could get a v8 3/4ton WT trim with manual transfer case but here it sits lol. Anyways, it rides bad. Hell, I'd call it beyond bad. I hit a crack in a parking lot and ABS engaged from the rear end jumping off the ground. Front's almost as bad. I put it on the lift and noticed what looks like the torsion bars being cranked, I'm assuming to level the truck? What position is stock? I also included a pic of the rear "springs" I'll be removing to make it ride like a vehicle again. They aren't bags but giant foam blocks. I highly recommend never purchasing a set.
