Give your gas tank a new custom look with one of our custom gas caps! We offer a number of options that will give your gas tank some much needed style. Replacing the stock gas cap on your Harley Davidson is a simple modification that will ensure you no longer have to live with your lame OEM cap. Some of the gas caps we offer have LED fuel gauges whilst others have simple unique designs as well as a variety of vintage looks for Old Skool choppers and bobbers.
