BILSTEIN B4 OE-Spec Rear Damper for BMW 3 Series F34 Gran Turismo and F30

Part number: 19-247038

Refresh the rear suspension on your BMW 3 Series with the BILSTEIN B4 OE-spec rear damper. This direct-fit unit restores the taut, composed feel you expect from a factory-fresh BMW, using BILSTEIN gas-pressure technology for dependable control, grip and comfort on British roads. Ideal when your original rear shockers are tired, leaking or knocking, and perfect for daily drivers who want stock ride height and OEM-matched behaviour.

We have fitted these at MJ Modifications and customer feedback has been consistently excellent. Owners report sharper turn-in, better stability over bumps and a smoother, quieter ride without harshness. If your 3 Series feels floaty or crashy at the back, this is the go-to OE-equivalent upgrade that simply works.
