Product Line Details

Bilstein B4 OE Replacement dampers are focused on preserving the original suspension character of the vehicle. This line is aimed at drivers who want factory-like comfort, steering response, and road control from a replacement strut rather than a performance upgrade. The 22-220080 follows that OE-replacement approach for BMW front suspension service.

What It Helps Address

• Front-end ride harshness on BMW sport suspension models
• Excessive bouncing after bumps or dips
• Reduced steering stability and road control
• Worn OE strut performance on daily-driven vehicles
• Uneven damping feel from aging front suspension components

Installation Notes and Tips

Verify the vehicle is equipped with sport suspension and does not use electronic suspension before ordering. This front strut uses a stem upper mount and base cup lower mount, so confirm the mounting style matches the original unit. A professional alignment is recommended after suspension service. This part cross-references BMW OE numbers 31 31 6 791 579 and 31 31 6 873 800 for the same application.
