Semi air-suspension enables the driver to adjust the suspension them self  by varying the pressure in the bellows the driver is therefore able to adjust the ride height, Left and right can also be adjusted independently making it possible to compensate a slightly uneven weight distribution and level the vehicle. Optionally a  compressor can be supplied. This is the most suitable solution for vehicles that are usually heavily laden and for the driver who desires to be able to vary the ride height manually.

Leaf Springs: On a vehicle with leaf springs, an air bellow is fitted between chassis and rear axle. This bellow supports the existing leaf spring. The VB-SemiAir is supplied as a dual chamber system. The bellows are not in connection with each other. Making use of a dual chamber system allows left and right to be separated, which enables one to level the vehicle even when it is loaded unevenly.

Torsion Bar: Al-ko rear axles are different from the leaf spring, the axle contains the springs in the form of torsion bars, as the steel twists(like wringing out a flannel) it provides resistance for the downward pressure of the vehicle.
