2010 GMC SIERRA 2500HD

This 2010 GMC Sierra 2500HD features our Conductor's Special 232 train horn kit. You can find the Shocker XL train horns included in this kit mounted in the spare tire location using custom brackets. Then the HornAir 232 onboard air system is mounted in the bed underneath the bed. The insanely loud Shocker XL train horns are hand-tuned to sound like a locomotive and they're the loudest horns we manufacture! Combining these with our 2-gallon 232 air system provides the horns with roughly 3-5 seconds of honk time and an air compressor capable of filling tires!
