Totally normal. This is the "built-in" factory caster which will get you about 3 degrees. In fact, it can use more than you even have there. I just did the "Caster Mod" and moved my lower control arm forward 3/4" and the caster went from 3 to 7 degrees. Drives like a totally different truck now for about 15 minutes of time drilling new alignment holes. Look it up and do it before you put the springs in.
