Hear these horns now!

Our budget-friendly train horn and our most popular onboard air system come together to bring you a train horn kit that gives you the volume and performance you need while taking it easy on your wallet. Our Rhino 244 Train Horn Kit sports a loud train horn tone that will stop you in your tracks and one of our best onboard air systems that can do so much more than just power your horns!

If you are looking for that deep, loud train horn sound, but you’re not trying to break the bank, our Rhino Train Horns are the horns for you. This three-chime black copper horn gives you all the power you need in a compact package that is perfect for vehicles with limited installation space. Our Rhino Train Horn comes with the required 1/4" solenoid valve already pre-installed to make installation that much easier.

Our HornAir 244 Onboard Air System that we paired our Rhino Train Horn with is an overpowered kit that not only powers your Rhino Train Horns but can also handle most pneumatic tasks such as tire inflation or powering air tools. Our 2-Gallon Black 6-Port Air Tank supplies enough air to give your Rhino Train Horn up to 8 seconds of continuous blast time. The workhorse Viair 444C Chrome Air Compressor that is included is a constant duty unit, meaning that it can run for extended periods without overheating all while still being fast enough to recharge our 2-gallon tank from 110-145 PSI in just over a minute.

As with all HornBlasters kits, our Rhino 244 Train Horn Kit comes complete with all required components and detailed instructions.

Great product

Placed these horns on our main loading tool excavator, drivers have no problem hearing the horns now after being loaded. Loud enough to hear over all engine noise.


Great horns for an even better price!

These train horns are wicked loud and are definitely worth every last dollar! This kit comes with everything needed and is very easy to assemble. Would definitely recommend if you're in the market for the best horns for the price!



Picked up this on sale last fall and have no regrets. The triple trumpets are big so make sure you have ample space picked out for it. The compressor is fast on refilling the tank. I have had several compliments for it and probably more complaints about them so it meets all of my expectations!


Great train horn kit

This is a very great train horn kit. The sound is very loud and sounds real! Good kit especially for a low price 1st time buyer.


Perfect set up to conceal on F-250

I have 2015 F-250. This is the perfect kit if you want the train horn sound with it all to be hidden! The tank and compressor (using additional compressor bracket) fit perfectly on the passenger side frame rail. I even have amp power steps and they clear nicely. Only thing that needs to be added to the kit in my opinion is a 90 degree fitting for the pop off valve being I had to install it on the side mounted to the frame rail. The rhino horns mount perfectly above the rear differential facing forward. Spare tire is still in place. The bells clear the DEF tank and 5 inch exhaust. Sound is great and they are very loud. I'm extremely satisfied with this kit for the price and the ability to hide it so well.
