After raising the front of my truck with the torsion bars and having it re-aligned i noticed the overload spring on the rear of the truck now touches the others in the rack, like having a lot of weight in the bed, when if fact the bed is empty. Is this nornal after raising the front? Thanks for all replys.

Just like jacking up the rear on a car loses traction and reduces weight on the rear, increasing the height of the nose, and decreasing the rake will do the opposit on your truck.
