2007 classic dually

max, i bagged my gmc dually a couple weeks ago and i get terrible negative chamber. i dont have the exact amount but i will measure it tomorrow. i just know when layed out 3/4's of my tire is off the ground. now i have djm drop control arms because i was running there drop kit. i dont have drop spindles. should i go back to the stock arms and get spindles? my toe also goes in and out threw the range. im running a 265/40/22 tire. its the same overall height of the stock 16's and tires that came on the truck. thanks in advance. hope you can shed some insight on this for me.

nice dually.  

I will almost always suggest drop spindles instead of A-arms. I will bet an ice cream sandwich that if you were to go back to stock arms and install some drop spindles that MOST of your alignment issues and camber issues will go away.

we talking vanilla or napolean???

thanks max, im going to ditch the arms and go to a mcgaughys drop spindle. how do you feel about raising the upper arm to get the arms parallel to eatchother. will that hurt me with my tierods? ive read a couple suspension books and i know the lack of chamber hurts me. but how will everything perform with the upper arm being shorter and parallel to eatchother at ride height? i cant seem to picture it in my head but threw the articulation of the suspension will the wheel stay at the 2 degrees negative chamber that they aligne my truck at? sorry if im sucking at spelling. ive noticed ekstensive and autocore do this. but this being my daily will it hurt me?   thanks again man.   and whenever i see ya ill get ya that ice cream.   josh

I don't know how moving the A-arms will effect the geometry.  The best way to tell would be to make a "paper doll" of the front suspension and move the points around until they do what you need without any issues.
