if this is what you are concerned about.. wait until the superlift.

there will be things that you need to worry about with it as well.

1 - front brake lines (guess what you have to move those too)
2 - rear brake line, its pretty damn tight after the lift
3 - ball joints
4 - CV angles
5 - alignment
6 - cam adjusters
7 - front driveshaft

overall i still think the Superlift kit is a strong well built kit but like everything else when you modify a truck you usually are effecting something else.

 

Exactly I think you nailed it head on by saying things will be changed when your dealing with something big like suspension but thats part of modifying.
