Like the title says i would like a front leveling kit but i am unsure about which size to use. I have a 2005 FX4

 

2.5 autospring

 

go with the 2.5"

 

If to do over again, I would go with the 2"... or go ahead with a real lift. My 2.5 inch worries me. We will see if my worries are real. I really don't like the upper ball joint angles and front drive shaft and rack and pinion angle to the tie rods. I do believe I will be seeing some wear a lot sooner than I want to. I didn't know they made a 3" leveling kit?? I would avoid that like the plague.

 

Alot of people have ran the 2.5inch and havent ever had problems.

 

I would go with a 2 or 2.5 inch kit. 3 inches is just too much for the ball joints to take.

 

look at the geometry of the components on a 04 up F150 with the 2.5... you may change your mind......

 

Try the 1.5" AS. Angles are not as severe and truck will sit damn near level. I got 2" from my 1.5".
Pictures in gallery.

 

wait... KY, you have a 1.5" lift?? Didn't know they made those...

Here are the angles on my 2007.

 

Before my lift the 2.5" AS gave me the pre-runner look.
