I have a set of Air Lift helper springs on my 3/4 ton truck. Installed them because I occassionally will hit above max load moving stuff. Back during the multi week polar vortex i noticed i kept loosing pressure. I did soapy water over the fitting and found nothing, then found one of the bags had a leak near the base of the bag. It was not due to slash or tear. The bag would lose all pressure within an hour. Outdoor temps had our highs in the low 20's. Fast forward to a couple weeks ago and we got much warmer highs and lows, when we got hit with a small 24 hour snow event. I filled the bags individually and hit the road. Came home, parked, and didn't bother looking at the airbags. I went to get a load of manure this past weekend and went to fill up the airbags and the bags were still the same pressure I set them to a few weeks back

So clearly the leak is temp related with the bag only. Is there any sort of rubber safe lubricant or leak prevention goo I can add to the bag to prevent degradation of cold weather performance? Winter time is when I need the bags the most because i load the truck heavy for snow pushing. Any additive I can add to the bags to keep them holding pressure in teh cold? Or do i need to add an air management system?
 
I've had two Firestone airbags develop leaks on the F350 with a cabover camper over the past 3 years. Both leaks were on the passenger side....near where the diesel exhaust system routed. Firestone did warranty the bags....but its a pain to constantly check pressure, or worse have to replace them.

AS BRTreedogs says...get a compressor system installed or switch to the solid Timbren "bags". I may fabricate a larger heat shield to try to extend the bag life on the passenger side...even though I'm not sure that heat is the issue causing failure?
