BILSTEIN B3 AIR SPRINGS: Perfection under pressure.
Preserving the original driving behavior should be the most important aspect when replacing suspension components. For the replacement of air springs there is no better than BILSTEIN. The BILSTEIN B3 air spring provides a perfect driving experience under high load, due to the constant counter-pressure in the bellows of the air spring. This is an optimum OE replacement for vehicles in which the air spring and shock absorber are installed as separate units.
