I have a 2003 Chevy dually with a full air ride system. The system is from Air Ride Technologies. It lowers that giant truck 9/14. The ride improved dramatically from stock and still maintains all towing and load capacities. Other items on truck include, Foose "Spank" wheels, Escalade door handles, smooth tailgate with relocated handle, steel roll pan, hidden hitch, Bed Rug bedliner, fiberglass tonneau cover, factory DVD player. The interior is dark grey cloth, front buckets. It only has 19,500 miles on it. The truck is white in color. Asking $39,000. Give me a call if interested. I can email some pics.
