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 main springs are used for vehicles that are regularly or constantly heavily loaded. For example, on a service vehicle or rescue vehicle. 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.
This is how reinforced main springs generally work:
Reinforced main 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 main 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 main 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 main springs are available for some models. This can be useful for vehicles that are heavily loaded.
Reinforced main or auxiliary springs are relatively inexpensive compared to other solutions for heavy payloads. Installing the springs is done in no time.
