Along with the genuine Mercedes-Benz parts, Bilstein says its B4 is the only shock absorber offering the unique DampMatic system

For more than a decade, many entry-level Mercedes-Benz models have been equipped with an additional suspension function based on a mechanical process. These models use the DampMatic technology developed by Bilstein.
Bilstein explains this is an amplitude-dependent control system that is fully integrated into the shock absorber. The models concerned are A-Class W168/W169, B-Class W245, C-Class W204/W205, GLC X253 and E-Class W212/W213.
However, Bilstein says this smart feature of the factory suspension is often unknown to independent garages and is hardly recognised when it is removed. After all, no cables or other visual features draw the attention to the DampMatic system.
Bilstein warns that if any aftermarket shock absorber is ordered, the suspension loses its additional function – unless the workshop has opted for the B4 series replacement shock absorber from Bilstein.
Along with the genuine Mercedes-Benz spare parts, Bilstein says this is the only shock absorber that offers the unique DampMatic system.
Bilstein says workshops do not need to take anything else into account when ordering spare parts, stating that if a Mercedes is already equipped ex works with the amplitude-dependent control system, this also applies to the associated Bilstein B4 DampMatic.
It says there is no need to decide between different product variants “with” and “without” and therefore no mistake can be made.
When it comes to how DampMatic works and why motorists should never do without it, Bilstein says the reason is the large damping force spread, which is made possible by a control piston.
Depending on the driving situation, the shock absorber behaves more softly or more firmly: as such, on a well-developed road, the passengers can enjoy outstanding rolling comfort, while on a serpentine road, dynamic attitude and agile handling are achieved.
Bilstein says the system reacts at lightning speed so that even unexpected evasive manoeuvres can be safely mastered.
Driving comfort, agility and safety are thus no longer conflicting demands; rather the centre of gravity is flexibly repositioned according to the situation and necessity.
Bilstein says of importance for the workshop is the fact that the installation is just like with any other shock absorber, as no cables, sensors or even an external control unit are required for this active system. The degree of complexity thus remains pleasantly low, and weight is also saved.
