Why Air Suspension Kits Are the Best Upgrade for Fiat Ducato, Peugeot Boxer & Citroën Relay Owners?

For many van owners, especially those driving a Fiat Ducato, Peugeot Boxer or Citroën Relay (Jumper), keeping the vehicle stable under load is one of the biggest challenges. Whether you use your van for deliveries, trades, campervan travel or long-distance touring, a rear air suspension kit is one of the most effective upgrades you can install.

This simple modification dramatically improves your van’s load support, ride comfort, safety, and handling — especially when carrying heavy tools, equipment or motorhome conversions.

 The Benefits of Upgrading to an Air Suspension Kit: 

Better Load Support for Heavy Cargo

Air suspension prevents the rear of the van from sagging under weight, keeping the vehicle level even when fully loaded. This is essential for commercial vans, delivery drivers, tradesmen and motorhome owners.

 

Perfect for Campervans and Motorhomes

Since many campervans and motorhomes are built on the Ducato/Boxer/Relay platform, adding air suspension provides:

• smoother travel
• better handling in wind
• improved cornering stability
• reduced body roll

 

This upgrade is considered a must for long-distance touring.

 

Longer Tyre and Suspension Life

A level vehicle means even tyre wear and less stress on leaf springs and the chassis. Over time, this saves money on maintenance and prevents premature suspension failure.

 

Improved Safety & Stability

Air suspension reduces swaying, bouncing, and rear-end instability — especially on uneven roads or during braking with a full load. Your van will feel more controlled and predictable.

 

Fully Adjustable for Any Load

You can increase or decrease air pressure depending on whether the van is empty or fully loaded. This flexibility makes air suspension extremely practical for both commercial and leisure use.

 

 

Who Benefits the Most from an Air Suspension Upgrade?

• Fiat Ducato owners (L1–L4, all roof heights)
• Peugeot Boxer commercial vans
• Citroën Relay / Jumper vans used for delivery, trade work, or heavy tools
• Campervan conversions and motorhomes
• Builders, couriers, electricians, plumbers
• Anyone carrying heavy or uneven loads
• Owners who tow trailers or caravans

If your van regularly carries weight, you will feel the difference immediately.

 

 Why Ducato / Boxer / Relay Vans Need Air Suspension?

Since these three vans share the same platform, they also share the same suspension architecture. While strong, the factory leaf springs often struggle with:

• rear-end sagging
• instability under load
• bouncing over bumps
• noise and harshness
• uneven tyre wear

A rear air suspension kit solves all these issues by adding an adjustable support system that works alongside the original springs.

 Quick Installation Guide (Simple Overview)

Installing a rear air suspension kit is straightforward and typically takes 1–2 hours.

1. Install Mounting Brackets

Attach the upper and lower brackets to the chassis and axle. Proper alignment is essential for smooth airbag operation.

2. Fit the Airbags

Position the airbags between the brackets and tighten once aligned.

3. Route the Airlines

Run the hoses to the back of the van, avoiding heat, sharp edges and moving parts.

4. Install Inflation Valves

Common mounting points: rear bumper or inside the loading area.

5. Inflate and Test

Start with 20–30 PSI.

Check for leaks and ensure both sides inflate evenly.

Most vans run best at 40–70 PSI under heavy load.

Performance You Will Notice Immediately

After installation, your Ducato/Boxer/Relay will feel:

• more stable
• smoother over bumps
• more controlled when cornering
• safer at motorway speeds
• stronger when carrying heavy tools or equipment
