Meet The Deniathan. Caleb’s once-standard 2018 GMC Sierra 2500HD, now a towering force of raw presence and sound. Featuring a massive 24" Stryker Suspension lift, 28" American Force Wheels, 40" Fury Tires, and Road Armour Bumpers, this Sierra is no ordinary build, it’s a statement on wheels.
And a truck with this kind of stature demands a horn that can match. That’s where the Nathan AirChime K5LA comes in, the gold standard of real locomotive horns. This isn’t a replica; it’s the real deal, reconditioned from retired locomotives with refreshed internals, hardware, and a sleek black finish, ready to blast with unrelenting force.
To support this heavyweight horn, Caleb installed our Goliath Train Horn Mount, fabricated from ¼” American Steel. This beast of a bracket holds a 5-gallon air tank and dual compressors, ensuring the K5LA gets the air it needs for 5–6 seconds of bone-shaking blast time. And with the option to add a second compressor, refill times are faster and performance stays at peak.
This build isn’t just loud, it’s legendary.
