2021 GMC Denali - S6 Shocker XL Horns + 228H Air System

Chris K. just leveled up BIG TIME! :loud_sound::rotating_light:

He outfitted his ride with our Shocker XL S6 horns :muscle::fire:, powered by the mighty 228H air system—and it sounds absolutely WILD! :exploding_head::boom:

But that’s not all… Chris went the extra mile with our Shocker XL Train Horn Mount, and even added the upgrade extensions to get all 6 bells lined up perfectly in a clean, aggressive row. :ok_hand::dart: This setup is not just loud—it’s downright beautiful. :heart_eyes::straight_ruler:





Major props to Chris for putting together one of the cleanest S6 installs we’ve seen! :100::clap: Welcome to the HornBlasters family, brother—you’re officially on the honker elite squad! :truck::dash::loud_sound::bomb: #ShockerXL #S6Squad #HornBlasters #MakeThemLookTwice
