Description Changing volume spacers in the shock is an internal adjustment that allows you to change the amount of mid-stroke and bottom-out resistance. If you have set your sag correctly and are using full travel (bottoming out) too easily, then you could install a larger spacer to increase bottom-out resistance. If you have set your sag correctly and are not using full travel, then you could install a smaller spacer to decrease bottom-out resistance.
