Overview

Upgrade your ride with the top-of-the-line Nathan AirChime K5 544K train horn kit. Experience the unmatched loudness and quality of the legendary Nathan AirChime K5 train horn, the gold standard in train horns. With decades of proven durability and reliability, this 5-chime die-cast horn is still the most widely used train horn today on the railroads. Paired with our heavy-duty 544K onboard air system, this kit gives you the best train horn experience possible.\n\nIMPORTANT: Our Nathan AirChime train horns are sourced from retired locomotives and undergo extensive reconditioning. This process includes sandblasting, a new black powder coat finish, and replacing all internal components such as diffuser rings, diaphragms, and cushion rings. This ensures each horn performs like new and retains its authentic locomotive sound.\n\nGet ready to sound off like never before with the Nathan AirChime K5 premium train horn kit from HornBlasters. This top-of-the-line kit features the legendary Nathan AirChime K5LA train horn, known for its unbeatable loudness and low rumble, and paired with the powerful HornAir 844K onboard air system.\n\nThe HornAir 844K air system, with its 8-gallon capacity and 1NM compressor, provides up to 8-10 seconds of earth-shaking honk time, making it the perfect match for the Nathan AirChime K5 train horn. With a 100% duty cycle up to 200 PSI, this system can handle not just your train horns, but also your air tools and suspension.
