An auxiliary air suspension system supports the existing suspension of the vehicle and enables the suspension to be adjusted within specific limits. Auxiliary air suspension systems are often added to vehicles that (regularly) carry heavy loads or sometimes have variable loads. An air spring is fitted between the chassis and the rear axle, which raises the ride height of the vehicle and generates greater spring travel. The auxiliary air suspension system therefore helps to increase the level of comfort and stability when travelling in your vehicle.

Our auxiliary air suspension system, also known as VB-SemiAir, is supplied as a two-chamber system. This means that the air springs are not connected to each other. The use of a two-chamber system allows left and right to be adjusted separately, enabling the vehicle to be levelled even when it is loaded unevenly.
