EVERYTHING BUT THE KITCHEN SINK.

So you want the most ridiculously stacked kit HornBlasters has to offer? Look no further! We asked people, "if you could build a kit any way you want, the sky's the limit, how would you build it?" What resulted is our Ultimate 12HB kit.

Here are the details:

We start with the absolute loudest train horn available. The Nathan AirChime K5LA. There is simply no substitute for the sound that comes out of this horn. These massive horns are made in the USA from die-cast aluminum with stainless steel diaphragms. They're built to withstand years of abuse from the elements, and the volume is something you will not only hear but feel as well. Hands down, the king of train horns.

Next up, we give you one of the biggest air tanks we carry, our 12-gallon 8-port air tank. This thing is HUGE! It's the right choice for this beast of a kit with plenty of air to run your air tools, your horn, air lockers, you name it. The tank features 8 ports: seven 1/2" ports and one 3/4" port with a max working pressure of 150PSI and a burst rating of 300PSI. This tank should give you enough capacity to blast your K5 for 10-12 seconds straight!

Ok, so we know you get the massive train horns & the gigantic air tank, what else could we have up our sleeve to power such a monster system? How about four constant-duty air compressors? The air compressors featured in this kit are some of the most powerful, rugged constant-duty air compressors that we carry. They will fill your 12 gallons of air without breaking a sweat and can recharge the tank from 110 PSI to 150 PSI in just about 65 seconds!  

So we've covered the insane parts that make up the heart and soul of our Ultimate K5 kit. Let's talk about all the extras that we include as well. We've thought of everything, and then we put it into the kit to make sure you are covered no matter the situation. Some of the other extras we include in this kit are:

• The electric drain valve kit lets you drain condensation from the tank from inside the cab with the push of a button.
• Our air relocation kit so that you can have another air outlet for inflating tires, toys, or running shop tools.
• Our 220 PSI digital air pressure gauge so you can keep track of exactly what the pressure is in your 12-gallon tank at all times.
• A HornBlsters tire inflation gun & 30' close-ended coil hose
• A blowgun, great for cleaning off dirt and mud, or blowing up inflatables.
• Plus various odds and ends to help you keep this kit blasting for a long time to come.
