Benefits of the Air Suspension Kit

Improved Ride Comfort

The system effectively absorbs shocks and vibrations, offering a smoother ride, even on rough roads.

Enhanced Stability and Safety

By adjusting the suspension according to the load, the vehicle maintains better road holding, reducing the risk of rollover or loss of control.

Reduced Component Wear

A properly adjusted suspension reduces wear on tyres and other mechanical components, thereby extending the vehicle’s lifespan.

Kit Components

The kit includes:

• 2 high-quality air springs
• Upper and lower mounts for secure installation
• High-performance air compressor
• Control panel with pressure gauges for precise adjustment
• Hoses and fittings required for installation 

These components are designed to fit perfectly with compatible Iveco Daily models.

How the System Works 

The air suspension system works by adjusting the air pressure in the air springs to change the vehicle’s height. This compensates for load variations, ensuring a stable and comfortable ride.

Kit Installation

Installation requires basic mechanical skills. It is recommended that you consult a professional to ensure correct and safe installation. The kit is designed for installation without any additional modifications.

The air suspension kit is added to the existing system, without replacing it. It consists mainly of two air bags, positioned between the chassis and the axle. Here are the details of the installation:

1. Partial removal of the original suspension: without removing the leaf springs, the shock absorbers and certain original mountings are removed locally.
2. Fitting of mounting plates: Lower
   plates: fixed to the rear axle, often using the leaf spring bolts or with specific heavy-duty clamps. Upper
   plates: fixed directly beneath the chassis side member, using existing anchor points or through-bolts.
3. Fitting the air cushions:
   The cushions (often made of reinforced rubber) are positioned vertically between the two plates, perfectly centred for optimal balance.
   They must not rub against the chassis or be compressed when deflated.
   
4. Installation of the air line: High-pressure
   hoses connecting each cushion to an on-board compressor (or a manual valve).
   Routing of the hoses through the side members, protected by sleeves or clamps to prevent abrasion.
5. Installation of the control system: In-cab electrical
   control: button + pressure gauge + solenoid valve, for inflation using an external compressor.

Servicing and Maintenance

Regular maintenance is essential to ensure the system functions correctly:

• Checking the air pressure in the cushions
• Inspect components for any leaks or wear
• Clean the compressor filters

It is advisable to follow the manufacturer’s recommendations for maintenance.

Comparison with Other Systems

Compared to traditional suspensions, the air suspension system offers:

• Adjustability: the ability to adjust the vehicle’s height according to the load
• Superior comfort: better shock absorption
• Increased durability: reduced wear and tear on components 

These advantages make it the preferred choice for transport professionals.
