Shawn G. just transformed his 2025 Chevy Silverado 3500HD High Country Dually with our Stealth 5-Gallon Spare Tire Delete Kit. This upgrade tucks a complete train horn system into the spare tire location, keeping the dually looking clean and aggressive while hiding the hardware out of sight.
The Stealth kit uses Shocker XL train horns paired with a 5-gallon 8-port air tank, stealth black compressor, and 150 PSI air system. Shawn’s High Country now has the same hidden horn power as a dedicated train horn build, without giving up bed space or cluttering the frame rails.
With 10–12 seconds of honk time and an average 2-minute refill from 0 to 150 PSI, this Stealth 5-gallon setup is a perfect match for a heavy-duty truck like the 3500HD dually. The install went smoothly and the result is a road-ready rig that can turn heads in traffic while staying completely stealth under the bed.
Huge shoutout to Shawn G. for trusting HornBlasters to take his Silverado to the next level. His 2025 Chevy Silverado 3500HD High Country Dually now has a hidden train horn system that backs up the truck’s size and presence with real Shocker XL sound.
