# Can I upgrade my Signature with the PRO2 components?

If you want to enjoy the increased capacity/added perks provided by the PRO2 brew head, you can upgrade your Signature *if it is PRO-enabled*: To check if it is PRO-enabled, confirm that there is a black, plastic adaptor ring sat on the red portafilter holder. This piece would be removed when using the larger PRO2 parts. 

Note you will need to purchase the complete [Full PRO2 Brew Head](https://flairespresso.com/product/full-pro-2-brewing-head/?__hstc=233546881.4b0367aca4ddae800dfef9f5eafbbfdf.1649620184124.1659365387323.1660336411748.27&__hssc=233546881.8.1660336411748&__hsfp=2541766894) to make this upgrade, even though you already have a Pressure Gauge set-up for your Signature (as the sizes are different). This kit will include everything needed for the switch, including the larger size PRO2 stem, plunger, dosing cup/tamper, and funnel - in addition to the brew head itself, of course. 

Signatures purchased before 2018 (or not equipped with the adaptor ring) are not PRO-enabled and cannot support this upgrade/the larger PRO2 parts.
