I lowered my truck 3 / 5. On the rear I used
American Muscle (<---- click link). I have 24x10 on 305/35/24. So now as I stand back and look at my truck... the passenger side wheel sticks out past the wheel well maybe about an inch and the driver side wheel is more under the wheel well maybe about an inch. Any idea how this could be??? Everything was nice and centered before the drop. I checked the rims to make sure there both the same width and which they are. I just dont understand how this may have happened. Its not that noticeable unless your someone like me who is super ocd and obsessed with my truck. I will have to take a pic of what I am talking about. But here is a pic of my truck anyway.

 

dumb question, but assuming you did an axle-over to achieve the 5" in the rear. have you measured spring perch to axle housing on both sides?

 

It's a "known issue" on all 04-08 trucks, still present on the 0o-14 trucks. It has to do with the way the truck is built. No one has a fix for it as far as I know. It's more evident with aftermarket wheels on stock suspension.

Look up bed alignment threads

 

The 3 / 5 drop looks Great.

I can't see all pics, but as I recall there is some slack between spring center bolts and holes ..... 1/2" shift takes 1/2 inch off one side and adds to the other.
