When it comes to building an unstoppable train horn setup, Nathan V. went all out! His 2021 GMC 2500 AT4 is now rocking the HornAir 544K Onboard Air System, Shocker S6 Train Horns, and a Viair Dual 444C Air Compressor Kit—all securely mounted on the Goliath Mount for the ultimate clean and professional install! 
With six massive Shocker XL horns and dual compressors pumping out air like a freight train, this setup is built for pure, unrelenting POWER! 
Whether it’s clearing traffic, waking up the neighborhood, or just flexing on the road, Nathan’s AT4 is bringing the noise in a BIG way! 
Who else is running a Goliath Mount setup? Let’s see those installs!
