We’re here to help you navigate through our selection to ensure that you choose the perfect kit for you!


But, What is a Train Horn Kit?
A horn kit, or also known as train horn kit, is a horn system composed by an air tank (necessary to store the compressed air which will be used to blow your horn), a compressor (the guy who pumps the air into the air tank) and a horn (the part that releases the air from the air tank).
Our clients mainly use it to substitute the usually weak horns that are present in a great number of cars: SUVs, pickups, 4x4s and so on.
Car manufacturers don’t seem to put a lot of effort in the car's horn, we are here to solve it!
Which is the best for me?
If you are a first-time-train-horn-buyer, you may not know which is the best option for you.
Don't worry! We have taken our 3 best sellers with different sizes, power and prices so you can make the best decision when choosing yours!




QUADRA-TRAIN-HORN® - MOTHER OF ALL HORNS
Sporting the same decibel levels as a small handgun, our QUADRA-TRAIN-HORN® literally gives you the most bang for your buck. Don’t let the small size or price tag fool you! This four-chime blacked out horn outputs a sound that could be described as a car horn on steroids.
Our QUADRA-TRAIN-HORN® is the simplest version of our horns, making installation much easier than in larger kits. With only a 22” by 9” footprint, Our QUADRA-TRAIN-HORN® is perfect for vehicles where install space is tight.
Please note that our QUADRA-TRAIN-HORN® is designed for the air source unit to be installed somewhere free of dirt and moisture, such as a trunk or a toolbox, and should not be installed on the exterior of the vehicle like some of our larger kits (e.g. the ones below).
Some basic wiring knowledge, some simple hand tools and our easy-to-understand instructions are all that's required to get up and going, making the QUADRA-TRAIN-HORN® perfect for beginners. If you are wanting to replace your weak factory horn with something that sounds similar and is much louder, this is a simple and cost-effective way to do so.
