This Top Drive air suspension kit is designed specifically for motorhomes with an AL-KO B1 chassis. It is intended for vehicles where the axle runs through the chassis and where the clearance between the tyre and the chassis measures 140 mm.

Built for Better Comfort and Stability

This air suspension kit helps maintain a more consistent ride height and supports the rear suspension when the vehicle is loaded. That can improve comfort, reduce harshness and help the motorhome feel more stable in corners and during manoeuvres.

Because the air pressure can be adjusted, the system can also be fine-tuned to suit different load conditions and driving preferences.
