Product Description

Double your air and double your fun by picking up our most popular Conductor’s Special Kit designed for our Spare Tire Dual Delete Bracket! Our Spare Tire Dual Delete Bracket cuts down install time in half and gives you a clean and compact way to install your Conductor’s Special 240 Train Horn Kit with twice the air! We even include the extra tank, fittings, and air line to make sure you have absolutely everything you need for your install. 

A train horn kit that can do it all and look good doing it, our Conductor’s Special 244K Nightmare Edition Train Horn Kit has been the go-to train horn kit for years. With enough volume to wake the dead and enough power to handle most pneumatic jobs you can throw at it, our Conductor’s Special 244K is one of our most rounded kits and a solid addition to any vehicle. 

Our Conductor’s Special 244K Nightmare Edition Train Horn Kit features our legendary Shocker XL Train Horns. Hand-tuned to the exact specifications of the US Train Horn Chord and packing just as much power as an authentic train horn, our Shocker XL Train Horns are the closest you can get to the real deal without having to spend thousands on a retired locomotive train horn. Constructed from an ultra-durable fiberglass-reinforced ABS composite with stainless-steel diaphragm and backed by a lifetime warranty against manufacturer defects, you get a train horn that is not only insanely loud but ridiculously durable as well. 

Of course, for horns of this caliber, you need an onboard air system that will keep up. Our Conductor’s Special 244K Nightmare Edition Train Horn Kit is one of our most well-rounded kits, with enough air to blast our Shocker XL Train Horns for up to 6 seconds, as well as handle most pneumatic applications such as air tools or tire inflation. Our Nightmare edition is powered by Viair’s 444C Stealth Black Air Compressor, recharging our 2-Gallon 6-Port tank in roughly a minute. With hardware and instructions included, you get everything you need to get back out on the road and honking. 

Just like our original Spare Tire Delete Bracket, the Spare Tire Delete Dual Bracket makes installing your train horn a breeze. A normal install without one of the Spare Tire Delete Brackets can take 6-8 hours. With our Spare Tire Delete Brackets, install time is cut in half with most installs taking less than four hours. If you are a DIY master, this is going to turn a full day project into a half-day project and if you are having it professionally installed, this bracket can pay for itself by saving you on hourly rates. Not only does our Spare Tire Delete Dual Bracket save you time and money, but it provides you with a professional and stealthy way to mount your horn kit with twice the air!
