Bilstein B4 DampTronic Front Right Shock Absorber OSF (EDC Adaptive) for BMW F20 F21 F22 F23 F30 F31 F32 F33 F34 F36 xDrive - OE Replacement Strut

Bilstein B4 DampTronic Right-Hand Front Adaptive Strut 23-266476 for BMW F-Series xDrive

Part number: 23-266476

Bring your BMW back to its factory poise with this right-hand front adaptive strut. The Bilstein B4 DampTronic RHF unit is the correct offside front replacement for F-Series BMW models with all-wheel drive and electronic damping. It plugs straight into the vehicle’s adjustable suspension system, keeps your driving modes working as intended and avoids dash errors. If your original electronic shock is leaking, knocking or has lost its composure, this OE-spec replacement restores the calm, grip and confidence you expect from a well-sorted BMW.

We fit these at MJ Modifications and run them on customer cars. Feedback is consistently positive, with owners reporting a return to supple ride quality, sharper turn-in and stable body control in Comfort, Sport and Eco Pro. It is the smart fix when you want original behaviour without compromise.

• Preserves all drive-mode adjustability and integrates cleanly with the car’s ECU and sensors
• OE-level fit and finish for quiet operation, consistent control and long service life
