         INTRODUCTION

Welcome to the Dunlop Systems and Components range of auxiliary air

suspension kits. As this catalogue shows, a wide range of solutions are

available to suit a multitude of vehicle variants.

Auxiliary air suspension is fitted in tandem with the standard steel springs of the

vehicle suspension, and provides enhancements in terms of both the stability of

the vehicle and the comfort of the passengers…

Vehicle Levelling

Simply by varying the air pressure in the springs, the vehicle can be

levelled both front-to-rear and side-to-side. Keeping the vehicle level

optimises stability, ensures correct headlamp beam distribution and

reduces tyre wear arising from uneven distribution of weight.

Straight Line Stability

Straight line stability is greatly increased at higher speeds, and when

subjected to buffeting from cross-winds or large overtaking vehicles

Reduced Body Roll

Body roll when cornering or negotiating roundabouts is significantly

reduced.

Fatigue Reduction and Wear Compensation

Suspension fatigue is reduced, so helping to prevent leaf springs from

sagging under repeated or constant loading.

Any sagging already present can be compensated-for. This is a particular

benefit for motorhomes, which are always fully laden.

Ride Comfort

Air springs help to absorb shock loads from uneven road surfaces,

therefore general ride quality is much improved.

...and furthermore...

Dunlop is an internationally recognised brand, approved by TUV

Dunlop Systems and Components is an air suspension specialist with a

history spanning more than 50 years, supplying in excess of 250,000 air

springs per year

Each system offered is optimised in terms of comfort and flexibility, by

designers drawing from an extensive range of air springs and bellows

Double and triple convolute bellows (i) are capable of operation at

relatively high pressure, enabling a correspondingly high axle load to be

supported and (ii) offer an extended suspension stroke, so providing a

wide adjustment range for vehicle levelling

VERY IMPORTANT NOTES

Gross Vehicle Weight (GVW)

Air assist kits are not in themselves designed to increase

the gross vehicle weight (GVW) rating of a vehicle. They

do not legally allow for carriage of a load greater than the

carrying capacity stated on the data plate of the vehicle.

Do not exceed the maximum load specified by the vehicle

manufacturer…

to avoid compromising passenger safety

to prevent possible damage to the vehicle

for legal reasons

Load Sensing Valve (LSV) Adjustment

If your vehicle is not fitted with an antilock braking system (ABS)

then it will have a load sensing valve (LSV) to automatically

adjust braking force under varying load conditions. This valve

must be adjusted immediately after the fitting of an air assist kit

and before the vehicle is driven again on public roads.

If the LSV is not adjusted following the fitting of an air assist kit,

it may misjudge rear load conditions to the extent that the

braking pressure applied to the rear brakes is not correct (e.g.

the rear wheels may lock with no load on the rear axle). The

consequences of this in terms of vehicle stability and safety are

potentially serious.

Vehicle Uprating

Despite the above words of caution, it is possible to upgrade the weight

rating of your vehicle. This must be carried-out by a specialist supplier

that will…

carry out any necessary modifications in addition to fitting the air

assist kit

complete documentation as necessary to inform the Vehicle and

Operator Services Agency (VOSA) – a mandatory requirement

supply and fit a new weight plate to replace the original plate

supplied with the vehicle

This process applies to United Kingdom registered vehicles. The process

in other countries may be different.

Maintenance

The system does not require very much maintenance other than…

- to maintain air pressure in the springs. Much like a tyre, the system

may lose a little air over time.

- to keep the air bellows clean. It is suggested that, when washing the

vehicle, the bellows are inspected and cleaned as necessary. Look in

particular for stones or grit trapped between convolutes, as this may

damage the bellow.
