Your suspension needs help

Trailers can add up to 75 kilograms of extra pressure on your towbar. You will notice it when driving as your car will become less stable on the roads. When your springs cannot handle the weight MAD’s helper springs can offer the solution!



This is how helper springs work

Many passenger cars are built for regular use. Most weight recommendations are calculated based on a lighter load. In practice, this can often be exceeded with extra luggage. 

Car manufacturers do not count on you to regularly load your car with heavy items; whether it is luggage, a bike rack or a trailer. Heavy trailers or caravans are also a problem. Helper springs are the solution.

An auxiliary spring is an extra spring that you can place next to or in the springs of your car. The helper springs from MAD help the existing suspension to bear the total weight and improve your cars driving comfort.

The car can handle heavier loads through caravans and trailers. Speed bumps and bumpy country roads are no longer a problem! This way you always reach your destination safely.

Helper Springs are Affordable 

Helper springs are relatively inexpensive compared to other heavy load solutions and can be fitted in no time at all.
