Heather’s 2010 GMC Sierra 2500 is turning heads and clearing streets with her latest upgrade—the Shocker S6 544K Nightmare Edition Train Horn Kit, paired with dual 1NM air compressors and a wireless remote system. This setup brings not only volume but reliability, power, and convenience.
The Shocker S6 is known for its authentic locomotive sound—sharp, loud, and impossible to ignore. By adding two compressors, Heather ensures that the system refills quickly, keeping her ready for back-to-back blasts without missing a beat. With the wireless remote, she’s in full control of the action, no matter where she is around the truck.
Installed cleanly and confidently, Heather’s Sierra isn’t just loud—it’s show-ready. Whether she’s at a meet, rolling down the highway, or parked at an event, this build delivers performance and attention with every honk.
What Makes This Build Stand Out:
-
Shocker S6 Horns: Six tuned horns for maximum volume and authentic train tone

Dual 1NM Compressors: Fast recovery time, high reliability
-
5-Gallon Tank: Extended honk time and consistent performance

Wireless Remote: Easy control from a distance

Heather’s build proves that the right combination of parts and style creates a serious showstopper. Loud, bold, and built right—this Sierra is a true HornBlasters masterpiece.
