2021+ FLOAT X2 Volume Spacer Installation

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.

Step 4

Remove or install Air Volume Spacers as needed, making sure not to exceed the maximum number of spacers for your shock's travel. Coat the air seals in a thin film of Slick Honey then reinstall the outer air sleeve with the air valve side first. Rotate the outer air sleeve until the tab on the eyelet aligns with the notch in the outer sleeve. Slide the outer air sleeve all the way to the negative air sealhead to engage the air seals. Reinstall the wire retaining ring making sure that it is fully seated in its groove.
