Have AIr Ride Air Bag Leveling kit and love it!!! Bought it for my '99 and took the bags off that truck when I traded it and put them on my2004. great support from Air Ride as well. I Needed new bolts and a couple of brackets when I made the switch. They sent them to me NO CHARGE!! Wasn't expecting that!! Like the option of being able to air down if needed for softer ride( Wife) . Complete system bolts on without any drilling or modifications. Anyway... Hope this info helps.
