Currently, we don't offer any air gauge options for the Softail models.
Generally, we recommend customers inquiring about gauges check into either Autometer or Dakota Digital as they offer numerous replacement gauges and mounting options. If a gauge is purchased from either of these companies, you will need a 5/32" air fitting, airline, and Y-fitting in order to connect the gauge to the rest of your air system. It is also important that if you decide to purchase a gauge, it must be at least a 300 PSI gauge.
The necessary fittings and airline can be purchased from our Products page.
