Bilstein B4 Rear Damper 19-217994 for BMW F20 F21 F22 F23 Standard Suspension

Refresh the back end of your BMW with this OEM-spec gas-charged rear shock unit from Bilstein.

Built to factory specification for standard SE suspension and stock ride height, it is a direct bolt-on solution that delivers the trusted Bilstein feel on the road.

Part number: 19-217994

Why this B4 rear shock makes a difference

  • Factory-spec fitment for BMW SE and standard chassis setups
  • Gas-charged design for consistent damping and secure road holding
  • Restores confidence under braking, cornering and on rough surfaces
  • Comfortable day-to-day ride with precise control when you need it
  • Engineered for durability with dependable performance over high mileage
  • Direct replacement that works with original springs and mounts

We have installed many B4 units in our workshop and customer feedback is consistently positive. Owners report tighter rear-end control, reduced bounce and a composed, quiet ride that feels like the car did when new.
