I just put a doetsch upper control arm, 3.5 lift spindle, and a 2.5 lift coil. Its not exactly where i want it and im thinking about throwing in a 1.5 poly spacer aswell. heres the problem. will the 4" coil/spacer work with my aftermarket control arm and spindle or is that too much? and i am getting it aligned in 2 days after i finish the lift and the guy asked my if my truck had cam bolts? When i put the upper c-arm on the bolts going through it had cams on each side ( kinda like a lop-sided washer ) is this what the guy is talking about? and will it be able to align right if i have a 1.5" spacer ontop of a 2.5" lift coil?

 

Its for a 2001 screw

 

Yes, those are camber bolts you installed. I think you will be fine adding the spacer.
