Unfortunately, we don't have a solid option for gauges and gauge mounts for the 2015+ Road Glides. The way the Harley Davidson designed the fairings, they left little to no usable space to mount a gauge. We've had a few customers come up with their own ideas of how to mount one of our gauges. Below are a few pictures to give you examples of those along with the links to our and Autometer's websites. If you choose to go with one of our gauges, they come equipped with all the extra components you need (i.e. airline, Y-fitting, cutter, gauge fitting, etc.), you will just need a gauge pod to mount it in.

Another option is to go with a billet rocker box mount from A1 Cycles out of North Carolina. If you chose to go this route, you will have to locate a 0-150 psi gauge that fits the dimensions of their mount as our gauges are much larger and are not compatible. At a minimum, you will still need the following components from us, an 8' roll of 5/32" airline, a Y-fitting, and a female push-to-connect fitting for the back of the gauge.
