I took my truck to a couple of places like firestone and they said a proper alignment could not be done because of the lift. Finally a place called corner stone automotive did an alignment "to the best of their abilities." That's where I'm at now.

Looks like a puppy that hasn't learned how to walk yet ?
Usually a lift causes the tires to lean out at the top. The drop pivot brackets bring them back in. Unless the brackets have too much drop for the lift and then you'll get what you have.
Check the drop brackets for the I beams and see if there's another hole a little higher up you can use.
You may be using a 6" drop bracket hole for a 4" lift. Lots of them have holes for both. The alignment shop should have known that.

Yeah my drop brackets do have two holes. The problem is Onarm is using the bottom hole on one bracket while the other arm is using the top hole on the other drop bracket. Would you know what hole would be for the 4in lift top or bottom

As you raise the frame of the truck up in relation to the wheels - which stayed back at ground level - you have to move the pivot point down. Down 4" for a 4" lift, down 6" for a 6" lift.
Top hole should be 4" bottom would be 6". That's the usual.
Just went through this with my son's F150 4x4 a couple of weeks age. He put a 4" set of springs in and the guys helping him used the lower holes. It looked broken with the tires so far in at the top and out at the bottom.
Moved the pivot bolt up to the higher holes and much closer. It still needs a proper alignment but it's driveable now.
Like I said the guys at the alignment shop should have caught that.
