WILL HAVE THE SMOOTHEST OF RIDES
WHAT IS AIRFLEX?

Airflex Air Ride Suspension utilizes a Torflex beam as the
foundation. This allows the suspension to maintain tire alignment
and rigidity without significant chassis modification. A special
mounting structure provides axle alignment post installation,
while housing the airbags.

PROTECT YOUR CARGO WITH AIRFLEX
AIRFLEX PROVIDES A SMOOTHER RIDE

• The hybrid design of the Airflex Air Ride Suspension and
TORFLEX Suspension absorbs and reacts progressively based
on shock.
• The air supply is interconnected between each wheel end,
allowing equalization or load sharing between air bags.
• Suspension system is also a load carrying cross member
that minimizes input by dispersing the load over a wide area.

Airflex Air Ride Suspension is delivered as a
complete assembly ready to be mounted to the
chassis. Available are Dexter Air Control unit
