Rear Electronic Damper For BMW F-Series With Adaptive Suspension - Bilstein B6 DampTronic - Part No. 20-250744

Transform the rear-end control of your BMW without lowering the car. This Bilstein B6 DampTronic rear unit is built for models equipped with BMW adaptive damping (EDC), giving sharper turn-in, better body control and confidence on British B-roads while preserving everyday comfort. It plugs straight into the factory electronic system, so your original driving modes remain fully functional.

If your original rear shock is tired, leaking or you want a genuine performance upgrade that still feels OEM-refined, this is the go-to choice. We run these on customer builds and the feedback is consistently positive for road use and fast-road driving.
