RockShox Rear Shock Volume Reducer

A volume reducer decreases the internal air space in your shock, which makes the spring rate more progressive. In practical terms, this means the shock will feel firmer as it gets deeper into its travel, helping you resist harsh bottom-outs on big hits without losing that plush, small-bump sensitivity at the beginning of the stroke.

You likely need one if you find yourself frequently bottoming out your rear shock on drops or jumps, even when your sag is set correctly. If you feel like you are blowing through your travel too easily, adding a reducer can provide the extra support you need.

No, compatibility depends on your specific shock model and its internal design. Always check your shock's service manual or the RockShox spare parts catalog using your shock's serial number to ensure this specific part fits your unit.

Installation is generally straightforward and doesn't require specialized shop tools, but you will need to be comfortable performing basic shock maintenance. You will need to deflate the shock completely and remove the air can, so have your shock pump and the appropriate socket or wrench for your air can handy.

Yes, depending on your specific shock model, you can often stack or swap reducers to fine-tune the progression. However, you must stay within the manufacturer's recommended maximum limit for your specific shock to avoid damaging the internal components.
