Behold Larry's 2019 Ford F250 Super Duty, a commanding presence at the 2021 SEMA Show—a build shaped by the industry’s top automotive brands into a visual and mechanical masterpiece. Towering on 28x14" Forged TIS Wheels and 42" Fury M/T Tires, with a lift from Stryker Suspensions and armor by Road Armor, this truck leaves no detail untouched.

But a visual powerhouse like this demands an equally formidable acoustic presence. Enter the Katrina 544K Nightmare Edition Train Horn Kit—Larry’s weapon of choice for piercing, locomotive-grade sound that mirrors the truck’s bold attitude.

Mounted seamlessly in the spare tire location, the Katrina Train Horn and 544K onboard air system form a tight, integrated setup, utilizing their underside feet to lock directly onto the frame’s cross members. The result is a clean install that keeps the system protected while enhancing accessibility.

This 5-gallon onboard air system not only delivers up to 10 seconds of honk time, but also serves dual purposes—tire inflation and powering small air tools when the job calls. It’s a blend of sonic dominance, functional reliability, and installation ease that elevates Larry’s F250 beyond typical show builds.

Ready to command attention like never before? Upgrade to the Katrina 544K Nightmare Edition Train Horn Kit today.
