Just purchased a 07 Screw FX4 and would like to level it what it the right kit to go with to make sure the front isnt higher than the rear.

 

Do some reading and see what the best results are. I suggest the AS 2.5

 

x2

That's the exact kit I had on mine before I lifted it.

 

I suggest the AS kit as well, but in the 2" version. The angles are not as extreme and mine is exactly level front and back.

 

check out my gallery. 2" as sits level!

 

I would go with the 2" as well

 

I went with the 1.5" AS, and the front sits 1/8" lower than the rear.
When you look at the truck from the side, it looks level.

 

I just purchased a 07 supercrew and want to level also. I am thinking about a 1 1/2 inch kit. Does anyone have or can anyone get a picture of each autospring lift on the same vehicle. To include comparison pictures of cv, ball joint, and tie rod angles.
