Ok we all know wut they are and wut they do but im wondering where did they originate from. I know semi trucks use them but arent those for their brakes or something to do with the braking system cuz whenever they stop u always hear that PSSST just like when a bagged vehicle drops. So did they kinda come outta the world of semi trucks and someone just reduce the size of the bag and think it would be a good idea to try it out as a suspension component?

 

the cab rides on the airbags. Also, sone of the suspension in the trailers and he rear of the rigs also have. depends on the truck.

They do use air for the brakes, but its not like bags used in your truck.

Not sure if they were first (like before airbags in slammed rides) but some older Lincolns use Airbags. As a matter of a fact, you have to turn them off when you lift them or the bags inflate while in the air and wont deflate when you drop them and then BOOM a bag blows. A guy I worked with in Atlanta leanred the hard way in a tire shop i worked in.
