Vans are often subjected to heavier loads than originally intended by the manufacturer. Tools, machinery, shelving systems, campervan conversions, trailer operation, or heavy cargo can cause the vehicle to lose driving stability, sway more, or visibly sag.

Depending on the vehicle and area of application, various chassis solutions are available. These include auxiliary air springs, full air suspensions, reinforcement springs, heavy-duty replacement springs, auxiliary springs, and heavy-duty front axle springs.

Which Chassis Solution is Right for Your Van?

The optimal solution depends on how your vehicle is used and what requirements are placed on comfort, driving stability, and payload.

Application Area	Recommendation
Variable Loading	Auxiliary Air Springs
Permanently High Payload	Reinforcement Springs or Heavy-Duty Replacement Springs
High Front Axle Load	Heavy-Duty Front Axle Springs
Motorhome	Auxiliary Air Springs, Full Air Suspension or Heavy-Duty Front Axle Springs
Trailer Operation	Auxiliary Air Springs
Cost-Effective Support	Auxiliary Springs

Auxiliary Air Springs for Vans

Auxiliary air springs are installed in addition to the standard chassis and support the rear axle as needed. The air pressure can be adjusted to the current load.

Advantages of Auxiliary Air Springs

• Vehicle remains level when loaded
• Individually adjustable air pressure
• Improved driving stability
• Less body roll
• More driving comfort with high payload
• Ideal for variable loading
• Support for trailer operation

Ideal for

• Motorhomes
• Tradesmen's vehicles
• Delivery vehicles
• Vehicles with trailers
• Vehicles with variable loading

---

Full Air Suspension for Vans

With full air suspension, air springs replace the standard steel springs. The system automatically regulates the vehicle height and ensures a particularly high level of driving comfort.

Advantages of Full Air Suspension

• Highest driving comfort
• Automatic level control
• Vehicle remains at the same height regardless of load
• Partial height adjustment possible
• Improved road holding
• Increased comfort on long journeys

Ideal for

• Motorhomes
• Campervans
• Comfort-oriented drivers
• Vehicles with high mileage

---

Reinforcement Springs for Vans

Reinforcement springs provide continuous support for the existing chassis. For vans with leaf springs, additional coil springs are often used to support the existing leaf spring.

Advantages of Reinforcement Springs

• Permanent chassis support
• Increased load capacity
• Less sagging when loaded
• Improved driving stability
• Maintenance-free solution
• No air pressure control required

Ideal for

• Vans with permanently high payload
• Vehicles with fixed conversions
• Motorhomes
• Service and workshop vehicles

---

Heavy-Duty Replacement Springs for Vans

Heavy-duty replacement springs completely replace the standard springs and offer higher reserves for vehicles with increased weight.

Advantages of Heavy-Duty Replacement Springs

• Higher load capacity
• Improved driving stability
• Less body roll
• Permanent solution
• Maintenance-free
• Ideal for permanent additional weight

Ideal for

• Motorhomes
• Vehicles with fixed conversions
• Vans with high continuous load
• Commercial vehicles

---

Auxiliary Springs for Vans

Auxiliary springs usually consist of an additional coil spring that is installed within the existing standard spring. They support the main spring when loaded and increase the reserves of the chassis.

Advantages of Auxiliary Springs

• Cost-effective retrofitting
• Support for the existing spring
• More stability when loaded
• Less bottoming out
• Maintenance-free solution
• Easy retrofitting

Ideal for

• Vehicles with occasionally higher loading
• Tradesmen's vehicles
• Delivery vehicles
• Price-conscious users

---

Heavy-Duty Front Axle Springs for Vans

Many vans carry a significant portion of their weight on the front axle. Heavy-duty front axle springs increase the reserves of the front axle and improve handling and driving stability.

Advantages of Heavy-Duty Front Axle Springs

• More reserves on the front axle
• Less sagging of the vehicle front
• Improved driving stability
• More precise steering behavior
• More reserves with high front axle load
• Maintenance-free solution

Ideal for

• Vans
• Motorhomes
• All-wheel drive vehicles
• Vehicles with high front axle load

Heavy-duty front axle springs can be used individually or in combination with auxiliary air springs, reinforcement springs, or heavy-duty replacement springs.

For Which Vans are Chassis Solutions Available?

Among others for:

• Fiat Ducato
• Citroën Jumper
• Peugeot Boxer
• Mercedes-Benz Sprinter
• VW Crafter
• MAN TGE
• Ford Transit
• Renault Master
• Opel Movano
• Nissan Interstar
• Iveco Daily

Depending on the vehicle, different solutions are available for the front and rear axles.

---

Load Upgrades for Vans

For selected vehicles, chassis solutions with load upgrade certificates are available. This can increase the permissible gross vehicle weight in many cases.

The possibilities depend on the respective vehicle, axle loads, and the chosen chassis system.

---

Common Areas of Application

Motorhomes and Campervans

Motorhomes often operate close to their permissible weight limit. Auxiliary air springs, full air suspensions, and heavy-duty front axle springs can significantly improve driving comfort and stability.

Tradesmen's and Service Vehicles

Tools, machinery, and shelving systems permanently increase the vehicle weight. Reinforcement springs or heavy-duty replacement springs often offer the best solution here.

Delivery Vehicles

For variable loading, auxiliary air springs offer maximum flexibility.

Trailer Operation

Auxiliary air springs help to maintain constant vehicle height despite tow ball weight and improve driving stability.
