Comparison Leaf to Air
Unladen
Leaf Suspension
Vehicle high at rear, Spring rate potentially
too high, Geometry not optomised, low tyre
friction, more body roll
Half Laden
Laden
Vehicle potentially level
Air Suspension
Level vehicle, Spring rate/Frequency correct for load,
geometry constant and optimised, Low tyre friction,
lower body roll
Level vehicle
Comparable but a smoother ride advantage for air
Vehicle low at rear, reduced bump travel,max
tyre traction, ride frequency changed
Level vehicle, full suspension travel, max tyre
traction, Spring rate/Frequency correct for
load
Semi-Air Suspension Kits offer the following:
• Level stance when vehicle laiden,
– Maintains suspension travel , better ride comfort
– Improves appearance
– Improves steering control & braking effectiveness
– Level headlight beams
– Reduces tire wear
• Reduced bottoming out
– Protective air cushion softens jounce-bumper engagement
– Increased suspension travel when loaded
• Reduced suspension fatigue
– Prevents leaf-springs from sagging under constant or repeated load
• Improved ride
– Spring rate matched to load
– Reduced bottoming
• Level off-center loads
– Individual inflation valves allow for side-to-side adjustment
– DO NOT EXCEED THE GVRW OF THE VEHICLE-
Frequently Asked Questions (Semi-Air)

•
How much air pressure should be in the air springs?
Air Pressure requirements vary from application to personal preference. A typical rule of thumb is a
minimum of 10 psi and a maximum of 100psi.
Do the air springs improve the ride?
When the vehicle is loaded, the air springs help the existing suspension carry the load and improve
the ride a great deal.
Do the air helper springs replace the existing suspension?
The air springs are attached to the existing suspension nothing is removed or altered.
Do the air springs increase the payload capacity of my vehicle?
The air springs maximise a vehicles carrying capacity within the vehicles GVWR (Gross Vehicle
Weight Rating). Do NOT overload the vehicle.
Will the air helper springs stabilise my vehicle?
Yes, the more air pressure you add the less vehicle movement you get in return.
What's included in the basic kit?
Nuts, bolts, brackets, air springs, air line and manual inflation valves. Everything is included for a
manual inflation system.
Can I have different air pressures in each air spring?
The ability to compensate for off-center loads is one of the best features of the air spring. Yes you can
have different pressures in each air spring.
Where should I mount the inflation valves?
The inflation valves should be mounted in an easily accessible location. We recommend placing the
inflation valves on or around the rear bumper.

Full Air Suspension (4 Corner Example)
Full-Air Suspension
Installation of the Full Air
Suspension Systems involves the
removal of the existing (original)
leaf or coil springs and replacing
with Air Springs so that the
Suspension is solely reliant on
the Air Springs..
Intelliride Full Air Control System
Driverite’s Full Air Suspension Systems
incorporate the electronic control package
known as IntelliRide.
Benefits of Full-Air Suspension
•
Greatly Improved Comfort
•
Improved Road Handling
•
Ability to lower the vehicle for easy access when the air is
exhausted from the air springs allowing the suspension to lower to
it’s bump stops
•
Multiple Height Settings Possible :– Access Height (For easy access and loading)
– Normal Ride Height
– Off-road Height (Speed Dependant)
– Motorway Height (Speed Dependant)
– Recovery Height
