Product Information

The Bilstein B4 is the OE replacement damper for the 997 generation 911, a monotube gas pressure unit valved to restore the factory ride and body control rather than change it. Gas pressure keeps the oil from foaming under repeated compression, so damping stays consistent over broken pavement and through long corners instead of fading. It measures 15.35 in collapsed and 21.24 in extended, mounts by an upper stem and a lower clevis, and carries a clear anodized finish. This damper is valved for cars on the standard suspension and does not fit a 911 equipped with PASM.
