Interesting that this thread popped up today.
I went to go get my alignment done and have the tech use the ICON Billet UCAs to get me with in spec. I asked the tech to place me at the higher side of the caster setting using the UCAs. Well after a lot of playing around he said he couldn't because the UCAs were to LONG! WTF. I am now in the red on caster on my driver side and just barely in the green on the passenger side.
When I installed the UCAs the heims and sleeves were all the way in (basically I did not touch the heim as per the instructions).
Did I get the wrong UCAs sent to me? The tech stated I could raise my truck some, which I know will cause our trucks to loose caster. Which I do believe since adding my skids I have sagged a bit both in the front and rear.
I ordered the ICONs through Metal Tech so I don't think the order would be wrong, but who knows.
Once I track down my measuring tape I will see what my fender to hub is. Any ideas will be gratefully appreciated.
