Chris K. took his 2021 GMC Denali to the next level with an ear-shattering setup featuring our Shocker XL S6 Train Horns, powered by the HornBlasters 228H Air System. This combination doesn’t just sound powerful—it is powerful. The S6 setup delivers a deep, authentic train horn tone that commands attention on any road.
To ensure a clean and professional install, Chris used the Shocker XL Train Horn Mount, along with horn extension upgrades that align all six bells in a sleek, aggressive row. This build doesn't just perform—it looks incredible, too.
Whether you're a fan of clean installations or loud, bold sound, Chris’ Denali sets the standard for both. It’s a perfect example of how to combine show-quality visuals with highway-dominating sound.
