Bilstein B6 14-18 BMW 328d xDrive Front Left Strut Assembly

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. Each damper is rigorously tested for quality that meets or exceeds OE standards and features application specific valve settings with a monotube design to bring out the best handling performance of a vehicle. B6 Performance (DampTronic) dampers will deliver improved safety and handling performance in a package compatible with factory electronic damping control. Twintube Strut Assembly.
