Shocker S6 544K Train Horn Kit

2010 Ford Expedition featuring Arturo R. running the HornBlasters Shocker S6 544K Train Horn Kit turned this full-size SUV into a true attention-grabbing setup built for both show and sound. The S6 544K Nightmare Edition packages HornBlasters’ six-bell Shocker S6 with a 5-gallon eight-port tank and 544K-class onboard air—part HK-S6-544K (white horn finishes ship as HK-S6W-544K).

Arturo R. installed the Shocker S6 544K Train Horn Kit with the white horns neatly mounted in the front grille area, creating a clean, integrated look that matches the truck’s all-white exterior. The grille-mounted setup keeps everything tight up front while still allowing the massive sound output the S6 544K is known for. The color-matched theme gives the Expedition a seamless custom build vibe while still keeping things functional and loud when it counts.

A clean install, aggressive sound, and a sharp visual match make this Expedition stand out whether it’s rolling into a show or hitting the road. HornBlasters lists 150 PSI operation with 110 PSI restart, roughly 8–10 seconds of honk time from the 5-gallon tank, and about 2 minutes to recover from 110–150 PSI under published test conditions.
