alright today i installed my adjusable uppers and adjustable lowers. i set them to the recomended spec for my lift per rough country with the drop brackets.

went to get it aligned and my caster is at 0 and my font drive shaft u - joints did not like the agnles to sat the least. the tech says i need to extend my lower arms out about half an inch, but i though caster was set by the uppers?

the uppers might have a half inch that i can adjust them in will that be enough to get 7 degrees?

thanks

 

You can adjust caster by upper or lowers. Shorten the uppers or lengthen the lowers. Either one will rotate the axle housing the same way, positive caster.
