I was driving down a back road at around 12am and wasn't paying attention and missed a turn, jumping over a sand dune about 30-40ft in the air and came down on the nose of the truck. This blew the airbags and most likely the shocks/suspension. How would I go about replacing the airbags. Can I just get two new airbags or do I have to get a switch module because I don't want to plug in new airbags and they blow up in my face? Also, any ideas on knowing if I need to fix shocks/suspension?
