Our BILSTEIN B4 is the reference for shock absorbers with gas-pressure. Our standard for your car guarantees a perfect driving behaviour – as on the very first day.
For an optimum driving experience and safety.
Over 60 years ago, we developed the monotube gas-pressure shock absorber for series production. The BILSTEIN B4 OE replacement series is available for most passenger cars – in both monotube and twin-tube shock absorber versions.
