RIDE WITH THE LEADER
TODAY’S LEADERS RIDE WITH
IRESTONE created a revolution in
the transportation industry when
it introduced the Airide air spring
in 1934. Today, Airide springs can
be found all over the globe on trucks,
trailers, specialty vehicles…even the new
Lincoln Town Car and Navigator.
Since deregulation, the trucking
industry has become fiercely
competitive, forcing fleets
to become far more
efficient than ever
before. In many cases,
it’s a struggle for survival.
That’s one of the reasons
why more trucks ride on
Firestone Airide air
springs than any other brand.
It’s a proven fact that trucks and
trailers with air suspensions
incorporating Airide springs suffer
much less “wear and tear” than those
riding on steel. This means longer cab
and vehicle life, lower operating costs,
less downtime and fewer failures of
expensive on-board electronic
equipment and accessories.
It’s also a fact that when your trucks
ride better, so does your cargo. Trucks
and trailers equipped with Airide springs
experience substantially less cargo
damage-and fewer damage
claims-than those that
ride on steel.
the obvious economic
benefits of air suspensions over steel,
driver comfort has become one of the
most important benefits of all.
Recruiting and keeping good drivers has
always been a problem, and with the
advent of national licensing it could
become a nightmare. With Airide, drivers
are more comfortable, more productive,
and less subject to accidents
caused by fatigue. Drivers have
always loved air suspensions.
Today, they demand it.
An investment in
air suspensions for
your tractors and
trailers is one of
you can make.
After saving you
dollars in reduced
and less vehicle
downtime, they pay you
back in hard cash at trade-in... sometimes
even more than your original investment.
Year by year, and model for model, used
tractors and trailers with Airide springs
are worth much more.

make big differences
on big rigs in big ways.
Primary Trailer Suspension Air Springs
provide outstanding cargo protection
while reducing maintenance problems
caused by road shock and “trailer hop”
when empty. Trailers last longer and can
be used to haul a wider variety of cargo,
reducing expensive empty trailer miles.
Lift Axle Air Springs allow you to lift the
axle without ever leaving the cab. Saves
tire wear under empty or partial load
conditions and lets you negotiate tight
corners with spread tandems.
Drive Axle Air Springs substantially
improve the ride and handling of the
tractor, resulting in greater driver comfort
and safety, less tractor maintenance,
longer tire wear and higher trade-in value.
They require little maintenance and last
more than twice as long as steel springs.
Front Axle Air Springs significantly
improve steering and handling while
improving tire wear and reducing
problems caused by cab vibration.
Cab Mount Air Springs eliminate most
problems experienced with standard cab
mounts and help reduce damaging cab
Seat Air Springs increase driver
comfort and help alleviate hazardous
HERE’S WHAT’S INSIDE THE
• Last at least twice, and as much as
four times longer than steel springs
• Require little or no maintenance
• Increase life of tires and brake linings
• Substantially reduce breakage and
maintenance of other vehicle
components, including electrical, air
conditioning, cab mounts, exhaust,
chassis, seals, wiring and drive train
Airide springs are available in single,
double and triple convolution types
plus reversible sleeve models for
virtually every conceivable heavy-duty
vehicle suspension application.
Stud. Manufactured as a permanent
part of the bead plate assembly for
maximum strength and durability.
Used to attach the spring to the
Combo Stud. Serves the dual
purpose of mounting the spring
to the suspension and providing an
entrance for air.
Blind Nut. Also a permanent part
of the bead plate assembly.
Provides an alternative mounting
system to the stud.
Air Fitting. Usually 1/4 N.P.T.
Provides an air entrance to
Bead Plate. Crimped onto the
bellows at the factory for a more
durable design and maximum quality
control. Allows 100% leakproof
testing prior to shipment.
springs can reduce your costs and increase your profits.
• Let you haul anything; eliminate
expensive deadheading runs
• Reduce driver discomfort and
dangerous fatigue; improve driver

Bellows. The “air bag” includes four
plies of material: an inner layer, two
plies of cord-reinforced fabric, and
an outer cover. Natural rubber
construction provides functional
properties to –65F.
Bumper. A solid rubber or engineered
plastic device designed to prevent
significant damage to the vehicle or
suspension in the event of a sudden
loss of air pressure in the spring.
Piston. Provides a lower mounting
arrangement for the air spring.
Controls the characteristics of
the spring under changing
Piston Bolt. Attaches the piston to
the bellows. Sometimes extended as
a means of attaching the spring to
the vehicle suspension.
Girdle hoop. A wire-wound ring
molded into the bellows to provide
lateral stability in convoluted
