By changing the in internal volume spacers in the shock you can adjust the shock's amount of mid stroke and bottom out resistance.

Assuming the sag is set correctly:

- A larger spacer will increase bottom out resistance if you are bottoming out too easily.

- A smaller spacer will decrease bottom out resistance if you are not using full travel.
