Stanley's 2011 Ford F250 Super Duty has one of our Conductor's Special 240 Train Horn Kit installed. From the pictures below you can see that he mounted all 4 Shocker XL Train Horns behind the grille as well as the air valve. Then the tank is installed in the front bumper right below the horns. The air compressor he was able to tuck into some space in the engine bay above the wheel well. This system features our Shocker XL Train Horns that have an intense loudness and authentic train horn sound. And with the 2-Gallon Air Tank and Viair 400C compressor, this air system will refill quick and give you the air to honk for about 5-7 seconds.
