Amortiguador - Bilstein B4
Cod. 19-103150 - BMW

Bilstein B4 OE Replacement dampers are specifically engineered to be the best choice for maintaining the original ride quality of your vehicle, while meeting or exceeding OE standards. These dampers are the ideal choice for the driver looking to restore the original performance and handling of their vehicle, with the added benefit of world-famous Bilstein quality.

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.

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.

Putting the pressure on.

Traditional oil shock absorbers, when put under extreme stress, can lead to oil foaming which causes shock fading and results in damping power reduction. In the 1950s BILSTEIN found the solution to this problem by developing gas-pressure technology. With the first installation of the monotube gas-pressure shock absorber on series produced Mercedes-Benz vehicles in 1957, we established the technology as an industry standard — a standard which continues today in both monotube and twin-tube designs. This means more reliable shock absorption and suspension under any load, and added safety in dynamic driving situations.

Perfect damping every day.

More than 90 % of all series vehicles are equipped with twin-tube shock absorbers. Twin-tube shocks utilize double-walled technology, where the piston divides the interior oil chamber into two working chambers. Under load, the piston pushes the oil down through the inner working chamber and up into the outer chamber. During rebound, the oil flows back through the piston valve to create a damping effect. Thanks to our close relationships with top automotive manufacturers, BILSTEIN can ensure all OE replacement shocks are designed to match the quality and performance of the original shock absorber

Original quality.

If the designation original equipment did not exist, it would have to be invented for us. For more than 60 years, we have been the development partner of choice for the suspension and shock absorber systems of renowned automakers — manufacturers in the premium segment as well as high-volume manufacturers. From the development of suspension components for series production to high-performance suspensions for motorsports or the production of high-quality OE replacement, our products and expertise are in high demand. Our comprehensive product range with high market coverage and availability includes everything — from OE replacement to tuning and motorsports. This is how we ensure the legendary BILSTEIN driving experience during the entire vehicle life.
