Bilstein B4 OE Replacement dampers are engineered to restore the original ride quality, handling and safety of the vehicle while meeting or exceeding OE standards. This unit is a twintube gas pressure strut for the front left corner, built with Bilstein Gas Pressure Technology so damping stays consistent under load and holds high power reserves. Bilstein supplies its struts in an unloaded state, so the box contains the damper and strut housing only. The coil spring, upper strut mount, bearing, dust boot and bump stop are carried over from the original assembly or sourced separately.
