Description
Dominate the road with the ultimate train horn and onboard air system. If you are looking for the loudest train horn for your truck alongside an onboard air system that delivers extreme power and unmatched reliability, this setup is built for you. This system is not for the timid, it is engineered specifically for drivers who want to command attention, turn heads, and run the most powerful train horn kit on the road. This direct-fit, 100 percent bolt-on train horn and onboard air system is engineered for maximum performance with zero hassle, requiring no drilling and no fabricating for pure, unapologetic power.At the heart of this system is an exclusive 100 percent duty-cycle waterproof air compressor, paired with a high-capacity, anti-corrosion-coated air tank built for long-term durability. When you hit the switch, the XCR 2.0 black-coated Demon stainless steel train horns unleash a blast so loud and aggressive it rivals a real locomotive, making it one of the loudest train horn kits for trucks on the market.True direct-fit installation means every component mounts cleanly under your truck using precision-engineered, powder-coated brackets that bolt directly to factory locations. This guarantees no drilling, no guesswork, no cutting, and an OEM-clean fitment for a stealthy, rock-solid installation that hits like a freight train.Built for long-term performance, every hose, fitting, and accessory is designed for long-term punishment and minimal maintenance. This complete kit includes a heavy-duty air hose, quick-connect fittings, a glow-in-the-dark inflator gauge, and all wiring and hardware needed for installation. For those who want even more power, you can add the BlastMaster Upgrade Kit (Model 6890) for a 30 to 40 percent increase in volume. This upgrade gives each horn its own dedicated heavy-duty brass solenoid and half-inch airline for maximum airflow and maximum output, making your setup one of the loudest aftermarket train horns available.

Return & Refund Policy – One Shot Powersports

Need to return or exchange an item? We’ve got you covered. One Shot Powersports accepts returns within 14 days of the original ship date, provided the item is new, unused, and in the manufacturer’s original packaging. Returns that do not meet these requirements may be subject to a restocking fee (details below).

Return & Exchange Instructions:

To begin a return, please download and complete our Return Form and include it inside the package with your returned item(s).

Return Shipping:

We strongly recommend insuring your return shipment for the full value of the item. One Shot Powersports is not responsible for any lost or damaged packages during return transit.

Please do not ship items using the manufacturer’s packaging as the shipping container. This often results in damage, and the item will no longer be considered “new and unused.” Items that are installed, scratched, damaged, or show signs of use will not be eligible for a full return and may incur a restocking fee or be denied entirely. If your return is denied, you will be responsible for return shipping if you want the item sent back to you.

Non-Returnable Items:

The following items are non-returnable under any circumstances:

  • All electrical-related products
  • All fluids, including oils, aerosols, grease, and similar products
  • Custom-built items (such as roll cages, powder-coated components, etc.), unless explicitly approved for return

If you’re unsure whether your item qualifies for return, please reach out to our customer support team before sending it back.

Refused Packages:

If a package is refused by the customer without prior approval from One Shot Powersports, the cost of return shipping will be deducted from any applicable refund.

Refunds:

Approved refunds will be issued back to the original form of payment.
