An air spring is basically a column of air confined within a
rubber-and-fabric container shaped like a bellows. The spring
action results from the compression and expansion of the air. When
used on road vehicles, air springs can keep the vehicle at a
constant standing height regardless of load.
Note for double convoluted air spring
Firestone double convoluted air springs DO NOT require a bumpstop
to avoid damage, however, your specific application MAY require a
bumpstop to maintain a safe ground clearance when deflated.
