I can't get beyond all that black stuff under the truck on the frame, springs etc. Mine all looks kinda "orangeish" They must have used a different color of paint on the frame axles and other parts and a different coating on all the fasteners on my truck.
You must be running your airbags at low pressure to have that kind of movement. I wish my F250 had that kind of give with the airbags aired down. Damn thing still rides like a truck for some reason!
