Johnny’s 1997 GMC Sierra 1500 now commands serious presence on and off the highway with the Conductor's Special 844K Train Horn Kit. The powerful Shocker XL Train Horns, hand-tuned to replicate a real locomotive’s chord, are mounted directly to the toolbox in the truck bed—delivering an unmistakable, earth-shaking blast.
Inside the toolbox, an 8-gallon air tank paired with dual constant-duty air compressors provides an impressive 12–16 seconds of continuous honk time. This massive onboard air system ensures the horns are always ready and provides plenty of air for inflating tires or powering small air tools when needed.
This setup is as bold as it is functional, turning Johnny’s Sierra 1500 into a truck that makes a statement every time the horn button is pressed.
