Reinforced main springs
Instantly find the right reinforced main springs based on vehicle data.
Reinforced main springs
MAD's reinforced main springs are ideal for use with a vehicle that is regularly or continuously loaded, as is often the case with light commercial vehicles. Thanks to these powerful coil springs, the vehicle maintains the ideal ride height and improves driveability and safety in loaded situations. As a result, the driver experiences optimum comfort.
Reinforced main springs are available if auxiliary springs are technically not possible. This occurs, for example, when the diameter of the original coil springs is too small, there is an end stop in the main spring, or when an auxiliary spring is not powerful enough.
Reinforced main springs are the ideal solution when the vehicle:
- is occasionally or constantly heavily loaded
- is too low when loaded, has too little ground clearance
- sags, bottoms out or hits the end stops
- is sensitive to side winds
- rolls over when cornering
- is unstable or sways when loaded
- does not steer directly

Reinforced main springs on front axle only
Does the vehicle hit the end stop of the main springs on the front axle? For example, at speed bumps or is the vehicle a bit 'directionless' at the front? Then reinforced front axle main springs are the solution. These reinforced main springs combine well with reinforced main springs on the rear axle or, for example, in combination with auxiliary air suspension.
Discover all the benefits of reinforced main springs
+ More ground clearance
+ Prevents sagging (static)
+ Prevents contact between the rear of the vehicle and the road surface (driving on/off ferries)
+ Prevents hitting the end stops of the suspension system
+ Prevents bottoming out (tow bar/rear end on speed bumps)
+ Reduces crosswind sensitivity and body roll when cornering
+ Improves road holding, stability and leads to more direct steering behaviour
+ Optimum traction with front-wheel drive
+ Prevents trailer or caravan swaying
+ Easy and quick to fit
+ Ideal when several drivers are involved
+ Reduces damage to the undercarriage
+ Contributes to safety
+ Long lifespan: metal parts are electrolytically galvanised
+ High-grade corrosion protection thanks to phosphating and epoxy coating
Extra powerful reinforced main springs
When you drive with a heavy payload, you demand more from the suspension system. That's why MAD offers reinforced main springs for different payload situations. For many vehicles, you can choose from basic support, medium support or maximum support. This is how we offer maximum comfort, control and safety.
All MAD coil spring systems are custom-made and extensively tested. As a result, they always fit the vehicle perfectly. This is how we guarantee the best quality.

What do you want to know about reinforced main springs?
How do reinforced main springs operate?
Many passenger cars, light commercial vehicles and motorhomes are built for "normal" use. They are calculated for passenger transport and average payloads. However: in practice, we often make optimal use of the available space and do not take the extra payload into account.
Reinforced springs are used for vehicles that are regularly or constantly heavily loaded. For example, on a service vehicle or rescue vehicle. Reinforced springs are available if auxiliary springs are technically not possible. This occurs, for example, when the diameter of the original coil springs is too small, there is an end stop in the main spring, or when an auxiliary spring is not powerful enough.
This is how reinforced springs generally work:
- Installation
Reinforced springs replace the vehicle's existing coil springs. These springs usually have a larger wire diameter and/or more windings than the original springs, resulting in a higher spring rate. This means the springs provide more force to keep the vehicle level up. - Increasing ride height
When reinforced springs are installed, the vehicle will be higher off the ground. This provides extra ground clearance, making it easier for the vehicle to pass obstacles with no or less damage to the vehicle's undercarriage. - Improved off-road performance
Increasing the ride height with reinforced springs can improve a vehicle's off-road performance. It provides more room under the vehicle for rocks, muddy terrain and other challenging conditions. - Adjustment to load
Medium support and maximum support reinforced springs are available for some models. This can be useful for vehicles that are heavily loaded.
Inexpensive
Reinforced or auxiliary springs are relatively inexpensive compared to other solutions for heavy payloads. Installing the springs is done in no time.

When does a car need reinforced main springs?
Although manufacturers of passenger cars and light commercial vehicles provide excellent bases, sometimes this is not enough. A vehicle may need reinforced springs in situations where the standard suspension is not sufficient to keep the loaded vehicle at the desired, safe ride height. Here are some situations where reinforced springs (coil or air suspension) by MAD can be useful:
- Heavy payload
If you plan to load the van or light commercial vehicle with heavy items, such as tools or construction materials, reinforced springs can help distribute the extra weight more evenly and keep the vehicle stable. - Loading solutions: tail lift, truck-mounted crane, EasyLoad or racking
When additional loading solutions are used, there will regularly be payloads that put extra strain on the original suspension system. Depending on the payload situation, auxiliary springs or reinforced springs can offer a solution. - Ride height
Auxiliary springs of reinforced springs are used to maintain the desired height, even with additional payload. - Safety and stability
Reinforced springs can improve the stability and driveability of the vehicle.
Examples of services with adapted suspension system:
- Parcel services and other distribution vehicles
- Delivery vans (with a tail lift, truck-mounted crane or EasyLoad)
- Service van
- Pick-up truck
- Fire fighting and rescue vehicles
- Motorhomes

Why is a certain type of suspension system not available?
Our suspension systems are developed and tested on a vehicle-by-vehicle basis. Has a vehicle entered the market fairly recently? Then the set may still be under development. In addition, a suspension system may not be technically possible on a vehicle. In that case, we offer alternative suspension systems.

Can I easily install reinforced springs by MAD?
Our suspension systems can all be installed by a specialist. Our reinforced springs come complete.
Maximum protection
MAD reinforced springs are made of high-quality chrome-silicon spring steel. All springs receive an anti-corrosion treatment and are then epoxied with the characteristic blue powder coating for beautiful and long-lasting corrosion-resistant protection.
