Unveiling a fusion of bold performance and clean execution, this 2010 GMC Sierra 2500HD now commands attention with our Conductor's Special 232 Train Horn Kit. Discreetly mounted in the spare tire location using custom brackets, the Shocker XL train horns unleash an explosive sound that mirrors a real locomotive’s roar—hand-tuned and built to be the loudest horns we offer.
Lift the bed cover and you'll find the HornAir 232 onboard air system, securely tucked away yet ready to perform. This compact but mighty setup includes a 2-gallon air tank and compressor, delivering 3–5 seconds of honk time—perfect for those moments that require an unforgettable blast. The system also offers practical utility, ready to inflate tires or power small air tools on demand.
This build is a perfect example of how to balance power, discretion, and everyday function in one powerful upgrade.
