Benefits of Semi Air Suspension
A semi air suspension upgrade works alongside your existing suspension to deliver a dramatically better driving and living experience
Vehicle Levelling
By varying air pressure in the springs, the vehicle can be levelled both front-to-rear and side-to-side. This optimises stability, ensures correct headlamp beam distribution and reduces tyre wear from uneven weight distribution.
Straight Line Stability
Straight line stability is greatly increased at higher speeds, and when subjected to buffeting from cross-winds or large overtaking vehicles — a major benefit on motorway runs.
Reduced Body Roll
Body roll when cornering or negotiating roundabouts is significantly reduced, making your motorhome feel much more car-like and planted through bends.
Fatigue Reduction & Wear Compensation
Suspension fatigue is reduced, helping prevent leaf springs from sagging under repeated or constant loading. Any sagging already present can be compensated for — a particular benefit for motorhomes which are always fully laden.
Ride Comfort
Air springs absorb shock loads from uneven road surfaces, so general ride quality is much improved — especially on UK B-roads and continental touring.

Semi Air Suspension for Motorhomes & Campervans
Volt Vans now offer professional semi air suspension installation for motorhomes and campervans. A semi air suspension system fits air bag springs alongside your existing leaf or coil springs, giving you the benefits of air suspension without replacing the entire system.
The result is transformative. Motorhomes running on a Fiat Ducato, Citroën Relay, Peugeot Boxer or Mercedes Sprinter chassis frequently suffer from a harsh, bouncy ride when fully laden — particularly at motorway speeds or on rougher rural roads. Air suspension solves this directly, with air springs absorbing shock loads and actively compensating for vehicle weight.
Levelling is one of the biggest practical benefits for motorhome owners. By simply adjusting the air pressure in each corner, you can level your vehicle on uneven pitches without levelling blocks — a significant quality-of-life improvement when touring.
Our mobile installation service means there's no need to take your motorhome to a workshop. We come to you — whether that's your home, a storage facility or a campsite — anywhere across the UK. Contact us today for a free, no-obligation quote.
Common Questions
Is it the same as full air suspension?
No — what we fit is assisted air suspension. It works alongside your existing suspension (usually leaf springs) rather than replacing it entirely. It's far more cost-effective but still delivers a massive improvement in ride quality and levelling.
Can I adjust it while driving?
Yes — most kits come with a gauge and valves so you can tweak pressures depending on load or road conditions. Upgraded compressor setups make this even easier.
Will it help with sagging at the rear?
Yes, massively. This is one of the main reasons people get it. It lifts the rear back to a proper ride height and stops that 'nose-up' look when fully laden.
Does it make the ride softer or firmer?
Both, depending on how it's set. It smooths out bumps but also reduces bounce and wallowing — so it feels more controlled rather than just 'soft'.
Is it safe and reliable?
Yes — these systems are very robust. As long as they're fitted correctly, they're low maintenance and widely used across motorhomes and vans worldwide.
Will it affect my payload?
There's no increase in legal payload, but it helps the vehicle handle weight much better. It's an important distinction — it improves how the vehicle manages the load, not the maximum you can legally carry.
How long does it take to fit?
Typically a few hours. In most cases we can complete the installation at your home, storage facility or campsite — no need to go to a workshop.
