Product Description

Double your air and double your fun by picking up our fastest filling 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 airline to make sure you have absolutely everything you need for your install. 

The Conductor’s Special 240, designed for people who don’t like to wait to blast their horns. We paired our insanely loud Shocker XL horns with one of the fastest-filling onboard air systems you can buy, allowing you to blast some of the loudest horns available as much and as often as you can get away with! 

For an onboard air system optimized from the ground up for train horns, there are no better horns to pair it with than the Shocker XL Train Horns. Hand-tuned to US train horn chord specifications, the Shocker XL Horns on our Conductor’s Special 240 give you the authentic tone of a locomotive with the volume to match. Constructed from an ultra-durable fiberglass-reinforced ABS composite with stainless-steel diaphragm and backed by a lifetime warranty against manufacturer defects, you can rest easy knowing this is the last train horn kit you will ever have to buy. 

What sets the Conductor’s Special 240 apart from our other Conductor’s Special kits is the speedy Viair 400C compressor. While it may not have as long of a duty cycle as other compressors in its class, it is one of the fastest-filling compressors available, allowing you to recharge your tank in less than 50 seconds!  Along with our water-resistant 2-gallon tank providing our Shocker XL Horns with enough air to honk for up to 4 seconds continuously, you get one of the loudest and fastest train horn kits you can buy.  

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!
