Henry’s 2001 Hummer H1 isn’t just built to turn heads—it’s engineered to demand attention. Outfitted with a fully custom Nathan AirChime K3 Train Horn kit, this install takes functionality and off-road durability to a whole new level.
All brackets and mounts were machined and handmade, ensuring maximum strength and stability even in extreme conditions. To preserve clearance underneath, Henry mounted the air system, compressors and tanks, on the roof rack, then protected it with a custom-built housing designed to deflect tree branches during off-road excursions.
Relays and air compressor filters were smartly relocated to a covered box for weather resistance, and additional air tool outlets were installed on both sides of the Hummer for trail-side utility. A custom switch bank was also installed in the center dash to control the horn, compressor, and other accessories with ease.
Finished in sleek black to match the H1’s rugged theme, even the Nathan AirChime K3 horns received the blackout treatment. The result? A tough, tactical, and thunderous build ready for anything.
