Product Details

The Bilstein B4 struts for the 2007-2013 Mercedes-Benz S550 (W221) is the part you fit when you want the car to feel like it did when it was new, not louder or firmer, just properly controlled again.

Inside is Bilstein's monotube design, with the gas and oil separated by a floating piston. That keeps damping consistent when the road turns rough and the unit gets hot, where a lesser damper would go soft.
