This is Eric's 2018 Ford F250 Super Duty Sema Build! He took this build to the 2018 Sema show. This truck has our Conductor's Special 244K Nightmare Edtion with Spare Tire Delete. This kit features our Shocker XL Train Horns that have a very intense loud authentic Train Horn sound. The Viair 444C Air Compressor provides the ability to use air tools or air up tires as well as for Train horns. Then the 2-Gallon Air Tank will give you about 5-7 seconds of honk as well. And now your installation has never been quicker and easier. The Spare Tire Delete bracket allows you to replace your spare tire with the entire train horn kit. With a few hand tools, some basic 12-Volt wiring knowledge, and a few hours of your time. You will be able to install this whole system!
