2008 HUMMER H2 SUT

Conductor's Special 244 Nightmare Edition Train Horn Kit

SOUND SAMPLE:

High Altitude Trucks brought serious attitude to the 2017 SEMA Show with their bold 2008 Hummer H2 SUT, and now it sounds as mean as it looks. Outfitted with our Conductor’s Special 244K Nightmare Edition Train Horn Kit, this build doesn’t just turn heads, it demands attention.

The kit features our incredibly loud Shocker XL Train Horns paired with the reliable HornAir 244K Onboard Air System, combining rugged durability with real locomotive sound. Mounted with precision, the horns perfectly match the Hummer’s aggressive profile, delivering a honk that’s just as unforgettable as the truck’s show-stopping presence.

This isn’t just an upgrade, it’s a transformation. The train horn system becomes an extension of the H2's personality: strong, unapologetic, and unmistakably loud.

Key Features:

  • Shocker XL Train Horns – Authentic train sound that matches the H2’s rugged style

  • HornAir 244K Air System – Onboard air with 2-gallon tank and constant-duty compressor

  • SEMA-Ready Design – Built to impress with both looks and sound

  • Nightmare Edition – All-black finish for a stealthy, aggressive vibe
