So a leveling Kit, or a spacer pack, or new coils will all do the same thing with the angles on the front suspension. They raise the frame of the truck away from the axle. The 5 links, 4 control arms and a drag link that hold the axle under the Truck stay a fixed length so the agle of the axle with respect to the road changes. This changes the alignment angle of the caster, and the drag link can also move the axle to one(drivers) side just a little bit. The lower arms do have a CAM adjustment on them so they can be moved to help put the caster back to where it should be. The Steering changes a little bit as well, I know it can create a bit of bump steer on a Jeep TJ, and without looking again I think the Dodge Truck front end is just like a TJ's.
With all that being said many people have lifted these rigs without problems.
