Bilstein B4 OE Replacement Air Suspension Front Left Strut for 2007-2013 Mercedes-Benz S550 RWD (W221)

Bilstein B4 struts bring the 2007-2013 Mercedes-Benz S550 (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.

Built in Germany to original-equipment standards and finished to survive road salt and grit, this is a bolt-in part with no modification required. Backed by Bilstein”s limited lifetime warranty.
