This replacement Air Lift damping knob extension is used to adjust the damping of your Performance series struts when the damping knob is located in a hard to reach area. These extensions are not required for all vehicles so if your kit didn't come with them and you don't have any issues reaching your damping adjustment knobs, you're all set! These are only sold in one size (250mm) so if they're annoyingly long for your application, you can easily cut them down to the desired size.
