Product Details
Bilstein B4 shocks bring the 2017-2019 Mercedes-Benz GLS550 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.
B4 OE Replacement air suspension parts replace the original air struts and dampers. Bilstein supplies air suspension to manufacturers, and these connect to the original connectors so they fit without modification and restore the original ride.
The monotube design is what sets Bilstein apart. A single high-pressure gas chamber keeps the oil from aerating, so the damping stays consistent on a rough road instead of fading as the unit heats up.
