The truck does have new springs all the way around. It's not a large difference in height between the front and rear, probaly something nobody would notice on the road or trail but I can see about a 1/4 to 1/2" difference when it's in the garage. I ordered them from AC/4x4parts.com and they said that it was normal and about the same difference front to rear as when the truck was new. I looked at it today when my 2 dogs were loaded into the back and it was pretty much level. I almost did the 2" spring lift that they offer but I just replaced the rear shocks a few months ago and couldn't justify doing new ones for only about an inch more lift. At any rate I would recomend the OME springs my truck really rides great, I haven't done any mudding yet but it felt good on a rough fire road.
