As a practical plug & play solution, our active BILSTEIN DampTronic® damping system offers the ideal upgrade for vehicles with factory electronic adjustment systems. As you drive, road variations are constantly measured by sensors and relayed to the CPU controlling the shock absorbers. This allows the dampers to constantly and automatically adjust themselves to the road conditions — for perfect traction control and stable handling. Our broad OE replacement range includes a large selection for Mercedes-Benz, BMW, Porsche and many other car manufacturers.
