How can I load my motorhome with additional air suspension?

Question

Accepted Answer

We offer additional load options for many leaf-sprung chassis by installing our additional air suspension. Under surcharge you will receive detailed information about this. You are also welcome to send your vehicle-specific inquiry Contact form place.

It is possible to increase the load on a motorhome with additional air suspension. An additional air suspension can increase the permissible total weight of the vehicle and at the same time increase the rear axle load, which enables more payload.

This is how it works

Installing the additional air suspension:
An additional air suspension is retrofitted to the rear axle and complements the standard suspension.
Increasing the axle load:
The additional air suspension supports the additional weight and thus enables the permissible rear axle load to be increased (when using suitable rims).
Adjustment of the permissible total weight:
Due to the higher axle load and the ability of the additional air suspension system to carry the increased weight, the permissible gross vehicle weight of the motorhome can be increased, e.g. B. in the Fiat Ducato up to 4,700 kg.
Steps needed:
An additional technical report and acceptance by the TÜV is required for the loading.
The relevant documentation must be entered into the registration office.
If it is necessary to increase the rear axle load beyond the standard level, tires and rims with a higher load capacity may also need to be installed.

Advantages

More payload:
You can take more equipment with you, such as: E.g. bicycles, SUP boards, awnings or other accessories.
Improved driving comfort:
The additional air suspension can stabilize driving behavior, reduce rocking and make the vehicle quieter.
Adjustable level:
The additional air suspension makes it possible to adjust the vehicle level using a compressor to raise or lower the rear.

How the calculation works

Without new wheels:
The new permissible gross weight is at most the sum of the axle loads in the registration document (field 7.1 front axle plus field 7.2 rear axle). Example: 1,960 kg at the front and 2,000 kg at the rear give 3,960 kg. The additional air suspension does not change the axle loads.
With wheels of a higher load rating:
The rear axle load may be raised to twice the load rating of one wheel. Rim and tyre must both prove this rating. Example: wheels rated at least 1,200 kg allow a rear axle load of 2,400 kg, and the gross weight then rises to up to 4,250 kg. The exact level is given in the certificate for the respective chassis.
Limit from the type plate:
The legislator allows an increase of at most 20 percent of the permissible gross weight stated on the type plate. If it says 3,500 kg, at most 4,200 kg is possible (3,500 kg plus 700 kg). If it says 3,650 kg, 4,250 kg can be reached.
What you need:
The registration document (fields 7.1, 7.2 and F.1) and a look at the type plate. In the product finder under suspension and load increase we guide you step by step to the right level.
