Air Premium X4

Automatic full air suspension for the front and rear axle

Motorhomes do not tend to be gentle fields of application for the majority of standard springs. The springs are permanently exposed to a heavy weight owing to the interior finish and equipment and loading is often uneven. Steel springs soon lose their tension under these conditions and the vehicle therefore loses some of its driving comfort and stability. Another consequence is the often seen sloping rear. Air suspension systems eliminate this problem.

AL-KO Air Premium X4 is an automatic full air suspension on the front and rear axle, which ensures a consistently high driving level and optimum suspension comfort. For this purpose, air spring struts are used on the front axle and air bellows of the rear axle. This enables automatic alignment to the optimum driving level and perfect levelling of the motorhome when parked. Premium comfort for your motorhome.

The Air Premium X4 with 4-corner full air suspension offers first class comfort in numerous situations. Virtually all impacts and vibrations are largely absorbed while driving. The motorhome can be automatically levelled on uneven pitches at the push of a button with the automatic levelling function. It is therefore no longer necessary to fit chocks, which is a cumbersome task. In addition, thanks to the flexibly adjustable gradient angle, ramps can be driven over without problems and the lateral tilt of the vehicle speeds up emptying of the wastewater tank.

You can raise or lower the vehicle while driving at up to 25 km/h with just the push of a button. This means driving onto a ferry no longer poses a problem. The front axle can be raised up to 70 mm and lowered down to 60 mm. The rear axle can be raised up to 40 mm and lowered down to 50 mm. The complete system is maintenance-free and also suitable for vehicles with ESP.
