This is Ryan's 2005 Ford F250 Super Duty, now equipped with one of the most iconic train horns in existence—the Nathan AirChime K5LA. Known for its deep, authentic sound, this horn was originally sourced from retired locomotives and meticulously reconditioned to like-new condition, bringing the unmistakable tone of a real train to the road.
The K5LA is not just about volume—it’s about history and craftsmanship. It delivers a resonant, multi-chime blast that commands attention and respect, setting Ryan’s build apart from typical aftermarket horn kits.
For mounting, Ryan fabricated a custom bracket that bolts directly to the spare tire carrier, tucking the horn neatly behind the bumper. This elevated position not only protects the horn from road debris and weather but also keeps the installation hidden for a cleaner, stealthier look.
With the Nathan AirChime K5LA installed, Ryan’s F250 doesn’t just honk—it announces its presence with the same power and authority as a freight train barreling down the tracks.

This build proves that form and function can go hand in hand—offering a refined install that doesn’t compromise on sound, performance, or appearance.
