Pat G. transformed his 2003 GMC Savana AWD into a road-dominating machine with the installation of the Conductor’s Special 127H Train Horn Kit. Known for its power and reliability, this kit includes our signature Shocker XL train horns, which are hand-tuned to replicate the unmistakable sound of a real locomotive.

Despite the van’s utility-focused appearance, this install proves that even an AWD workhorse like the GMC Savana can deliver unexpected performance and presence. The horns are powered by the HornAir 127H onboard air system, providing up to 120 PSI of pressure and just the right amount of honk time to deliver a deep, resonant blast whenever needed.

Mounted with precision and care, the Shocker XL horns are positioned to maximize sound projection without compromising the van’s functionality. Whether Pat is navigating busy urban traffic or cruising the open highway, his horn system ensures he’s heard clearly and unmistakably. This setup doesn’t just improve safety—it also adds a bold, attention-grabbing character to his build.

The 2003 GMC Savana may not be the first vehicle you’d expect to see with a powerful train horn system, but Pat’s installation shows how versatile and adaptable the Conductor’s Special 127H Kit can be. From commercial vans to recreational vehicles, HornBlasters kits bring professional-grade sound and impact to virtually any platform.
