Brian's 2006 Dodge Ram 1500 roars to life with the thunderous tone of a locomotive, all thanks to the stealthy installation of the Nathan AirChime K3 Train Horn. Carefully tucked behind the front bumper alongside the air compressor, the horn remains out of sight yet packs an explosive auditory punch when unleashed.
This clean and calculated setup maintains the truck’s sleek exterior while delivering unmatched volume and authority when it matters most. The dual 5-gallon stainless steel air tanks, installed in the truck bed, supply a massive volume of air—enough for up to 10 seconds of honk time—ensuring every blast is long, commanding, and impossible to ignore.
More than just a showpiece, Brian’s installation offers practical benefits as well, providing an onboard air system capable of powering accessories or inflating tires. The blend of form, function, and raw acoustic force makes this one of the most well-rounded and impactful train horn installs on the road today.
