winter time

What could i use to insulate my valves on my airride? It was below frezing this morning and i could not adjust the back... i got it up but it won't go back down. Thanks!

You can use air brake antifreeze. Best solution is to swap your electric valves for manuals inside the cab for the cold season, that's what I did few years ago when I used to drive my air bagged truck in winter and I never had any problem. Cuz up here when I say cold, I mean very cold. Another easy solution is to leave it aired up if your 100% sure you have no leak
