VB Air Suspension for LCVs

VB Air Suspension for LCVs

VB-FullAir-rear-axleWith more LCVs on the road for longer, often carrying heavy, sometimes fragile payloads and driving on the bump stops day in and day out, air-suspension has become an increasingly important option.

Whether the objective is for improved ride comfort, increased stability, protecting goods in transit or for enabling a vehicle to lower or raise for easy access, Rosmia can fit the right system. VB-Airsuspension manufactures air-suspension for virtually every make and model of LCV.

All the kits fitted by Rosmia’s engineers bolt-on to existing chassis mounting points and require no welding, cutting or drilling so your vehicle warranty remains valid.

Crucially all VB Air Suspension kits come with the necessary certification and approvals including VOSA and VCA.

vb-airsuspension-logoOptions include FullAir suspension, SemiAir suspension and uprated coil springs.

On this page we have summarised the benefits of each product.

Please book a LCV healthcheck if you would like to discuss which products are suitable for your vehicle.

Why consider VB Air Suspension?


  • Your vehicle is much more stable and less sensitive to crosswinds.
  • You will notice a big reduction in leaning and rolling when cornering.
  • Whether fully laden or completely empty your vehicle will be at a perfect ride height. When you drive a fully loaded vehicle without air suspension you can be driving on the bump stops and because the steel suspension cannot be adjusted you feel every crack, hole and undulation in the road. When unladen, your vehicle can feel light and unstable.  With air suspension the air bags can be inflated manually or automatically depending on the system you choose.

VB-FullAir – benefits

VB-FullAir is a fully automatic (adjustable) solution for suspension problems.

The existing leaf, coil-spring or torsion bar suspension is replaced by a complete air-suspension system (including air springs, shock absorbers, a compressor and an electronic control unit). The new air-spring system is controlled electronically via height sensors, a central control unit and a compressor and valve block.

Rosmia fits systems for any of the following:

– Both front and rear axles (VB-FullAir 4C).
– Rear axle only (VB-FullAir 2C)
– Front only (VB-FullAir 2C)

On the road

  • Road holding and stability is greatly improved as is comfort.
  • The VB-FullAir system automatically monitors and corrects your vehicle’s ride height. This ongoing process of monitoring and correction makes your ride comfortable and safe, whether your vehicle is empty or fully laden.
  • Off Road gives a higher vehicle and more ground clearance for off road terrain up to a driving speed of approx. 25km/h.

And when stationary:

It is possible to raise and lower the height to ease loading and unloading.

VB-SemiAir benefits

VB-SemiAir suspension has been designed for vehicles with heavy, or uneven loading, or for applications where the maximum payload is required for a large part of its working life.

The standard leaf springs are not necessarily designed to cope effectively with full axle loading all the time and often the standard suspension can struggle. VB-SemiAir provides a cost effective way of up-rating the suspension to cope with the requirements of a fully laden vehicle.

It acts as a helper to the original rear springs, keeping the vehicle level and stable. Even when your vehicle is fully laden, each air bellow on either side of the vehicle can be individually controlled for even ride height.

VB-Coilsprings Benefits

Rosmia’s engineers also fit uprated Coil Springs to LCVs

  • Uprated coilsprings can provide a 50mm-80mm increase in ride height at the front. This increases the clearance and stability of the vehicle.
  • They work well in conjunction with the FullAir and SemiAir systems at the rear.
