Bilstein B4 Rear Damper - BMW F20 F21 F22 F23 M Sport - Part No. 19-218014

Give your BMW its crisp, confident feel back with this Bilstein B4 rear damper for M Sport chassis. Designed to match factory calibration, this gas-pressure back axle unit brings back tight body control, smooth ride quality and stable road holding without adding harshness. If your car feels floaty, bouncy or knocks over bumps, this is the go-to replacement to sort it properly.

The Bilstein B4 uses gas pressure technology for consistent performance under hard braking, quick direction changes and rough British roads. It is a direct-fit replacement that bolts straight on, works perfectly with standard M Sport springs and restores the precise, planted character enthusiasts expect from a well-sorted 1 Series or 2 Series.

Why this B4 rear unit is a smart choice

• Factory-spec calibration for M Sport suspension - no unwanted stiffness, just the correct OEM feel
• Gas pressure design for reliable damping and predictable handling in all conditions
• Plug-and-play fitment on the rear - no modification required
• Improves stability, traction and comfort on daily drives and motorway miles
• Ideal fix for tired or leaking shocks, MOT advisories and high-mileage refreshes
• Works perfectly with original springs and top mounts

At MJ Modifications we have installed and supplied many Bilstein B4 kits to BMW owners. Feedback is consistently positive - customers notice tighter control, reduced bounce and a smoother, more composed ride straight away, all while keeping the authentic M Sport feel.
