I had the Air Lift bags on my 14 Ram Ecodiesel, but could not get the fittings on top of the bags to stop leaking (I think I scratched the little brass fittings during install). So i replaced the Air Lift bags with bags from Timber Grove enterprises. They were more expensive - about $400, but are very heavy duty and well made. Instead of stuffing a bag inside the coil spring, these bags mount on the axle to the brackets that would attach the factory air suspension. They also use heavy duty tractor trailer type air fittings and lines. Just another option for your consideration.
