Bilstein B6 24-319058 Rear Damper Upgrade for BMW F40 and F44 xDrive

Give your BMW’s rear end the control it deserves with the Bilstein B6 rear damper, part number BILSTEIN-24-319058 (also referenced as 24-319058). This gas‑charged monotube unit is a direct bolt‑on replacement for the rear axle on BMW 1 Series F40 and 2 Series Gran Coupe F44 xDrive variants including M135i xDrive, 120d xDrive, 220i xDrive, 228i xDrive, M235i xDrive and 220d xDrive.
