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:

• 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 optimizes stability, ensures correct headlamp beam distribution and reduces tire 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 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.

• 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 recognized brand.
• Dunlop is an air suspension specialist with a history spanning more than 50 years, supplying in excess of 250 000 air springs a year.
• Each system offered is optimized in terms of comfort and flexibility, by designers drawing from an extensive range of air springs and bellows.
• Double and triple convolute bellows are capable of operation at relatively high pressure, enabling a correspondingly high axle load to be supported and offer an extended suspension stroke, so providing a wide adjustment range of vehicle required.
• Auxiliary air suspension systems are fitted relatively quickly and easily, with no welding or drilling required.

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 tire, 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.
