Air Assist Kits
Air Suspension Parts
Welcome to the Dunlop range of auxiliary air suspension kits. You’ll find a wide range of solutions 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 passenger:
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 optimizes stability, ensures correct headlamp beam distribution and reduces tire wear arising from uneven distribution of weight.
Straight line stability is greatly increased at higher speeds, and when subjected to buffeting from cross-winds or large overtaking vehicles.
Body roll when cornering or negotiating roundabouts is significantly reduced.
Suspension fatigue is reduced, so helping to prevent leaf springs form 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.
Air springs help to absorb shock loads from uneven road surfaces, therefore general ride quality is much improved.

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
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.
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:
The system does not require very much maintenance other than:

To complement the extensive range of auxiliary air suspension solutions for conventionally-suspended vehicles, shown on the remaining pages of this catalogue, There are different Dunlop kits suitable for vehicles fitted with an AL-KO (Alois Kober) galvanised steel chassis (all variants 1994 to present and for double rear axles tandem). One of the greatest advantages of choosing a Dunlop kit for the AL-KO chassis is short installation time - there is no need for disassembly of either the drum or disk brakes. This makes possible an installation time for suspension parts of less than 2 hours. Starting from 1994 there are different types of air suspension available. depending on model and building year. All of these kits are designed for Fiat, Citroen and Peugeot vehicles. For Renault, Volkswagen Karmann, Opel and Vauxhall the kits are not suitable. Tandem axles can need some modification.
VERY IMPORTANT! All our AL-KO air suspension kits are not suitable for “Up Going Chassis’’!
In order to take full advantage of Dunlop AL-KO kits, it is prescribed that inflation Option 2 or Option 3 is chosen

For decades DSC Nederland has been manufacturing Dunlop air suspension for motorhomes, vans, and pick-ups. Every air assist kit consists of specially designed strong steel fasteners and large, strong air bellows that can be operated independently.
The PLC air assist kit 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 passenger.
