I have a '15 F-250 with the RC 4.5" Lift (added 2" block in the rear and a 2" Add a Leaf). On my '08 I was able to buy a Firestone Air Bag Kit that mounted on top of my leaf springs and to the outer-side of my frame. I can't find a kit like that for my '15. Does anyone know if the kits that mount to the axle will work with a lifted truck?
