Am interested in the new air ride for in a 1500. Need to know what the seat height is in the lowered position. We have a 2002 Dakota Crew cab and the height from the ground to the seat cushion is 30 inches.I measured a 2012 quad cab and the height is 40 inches. Are there any lowing kits to get 2012 lower? We need about 30 inch height as we are older and cannot get into a high pickup.
