Bilstein B4 OE Replacement Air Suspension Front Left Strut for 2012-2013 Mercedes-Benz S350 (W221)

Bilstein B4 struts bring the 2012-2013 Mercedes-Benz S350 (W221) back to its factory ride. When the original dampers wear out a car starts to float over crests and patter over broken pavement, and this is the fix.

Bilstein has built suspension in Germany since 1954, and supplies the same engineering to manufacturers as original equipment. The build quality is the reason these outlast what they replace, and they are covered by a limited lifetime warranty.
