The gas-pressure shock absorber type B4 DampTronic will be the replacement for standard parts in best OE quality, offering constant damping under any load, precise handling and high traction. “Better than the original” was the principle for the development of the BILSTEIN B6 DampTronic shock absorber, that features twin-tube or mono-tube upside-down technology. It delivers uncompromising road holding and increased tracking stability even in extreme situations, for example when pulling a trailer or with a heavy load in the vehicle.
