SemiAir is engineered to support the existing factory suspension and in turn, create more spring travel, particularly when heavily laden.

The use of dual-chambers allows both near and off sides of the vehicle to be pressurised individually.

This is useful if one side of a conversion is heavier, for example if there is a workstation or cherry picker on one side of the vehicle.

VB-SemiAir suspension can even out the vehicle weight distribution between both front and rear axles when pressurising the air bellows correctly, in turn improving stability, drivability and safety.
