THE FULL STORY

STEALTH SPARE TIRE DELETE® KIT

BE HEARD AND NOT SEEN 

You asked, we answered! The Stealth Spare Tire Delete kit is now available! After many hours of engineering and design, we've developed a train horn kit that not only fits more full size trucks and SUV's, but when installed has a lower profile than any other system before. With the bells tucked away, this new sleek configuration gives you the ability to be heard and not seen.

New features include:

  • Multidirectional horn mounting pattern; sound projecting from both sides creates a 360-degree wall of sound.
  • Fits more vehicles than before. New design allows for multiple mounting configurations.
  • New component layout gives 5" of extra ground clearance compared to the previous Spare Tire Delete kit by moving the bells up into the spare tire well.

Important Notes:

  • Fits most full-size pickups and SUV's. 
  • The spare tire delete kit is shown assembled above for illustration purposes only. The kit will arrive as individual components and assembly will be required. Please check the install instructions in the section below.
  • This bracket is NOT compatible with the S6 mounting extensions. The additional bells must be mounted individually. 

STEALTH WITH A SIDE OF EXTRA AIR 

Command attention with the 5-Gallon Stealth Spare Tire Delete Train Horn Kit-your all-in-one solution for powerful, road-dominating sound. This complete kit is designed for seamless installation in your spare tire location, delivering the iconic train horn blast you expect with a sleek and discreet setup.

Featuring a 5-gallon air tank, this kit provides extended air capacity to keep your horns honking longer. Paired with our extremely popular Shocker XL train horns and 544K onboard air system, it’s perfect for making sure you're heard when it matters most.

  • Complete Train Horn Kit: Includes everything you need-train horns, 5-gallon air tank, compressor, all mounting hardware, and more.
  • Stealth Installation: Fits neatly in your spare tire location for a clean, low-profile look.
  • Massive Air Capacity: The 5-gallon tank provides roughly 10-12 seconds of honk time and reliable performance.
  • High-Performance Sound: Designed to deliver the powerful, authentic train horn tone you demand.
  • Versatile Air System: Use it for honking, inflating tires, or powering small air tools.

Perfect for truck owners and enthusiasts who want unmatched sound and functionality, the 5-Gallon Stealth Spare Tire Delete Train Horn Kit delivers everything you need to make your presence known on the road.

OUT OF SIGHT

The Stealth bracket places the horn bells higher in the spare tire well and points them outward on both sides.

ALL-IN-ONE SOLUTION

Horns, bracket, tank, compressor, valve, wiring and fittings come together. Assembly and installation are required.

THE BRACKET
IS THE DIFFERENCE.

A purpose-built mounting platform replaces the spare tire. Its low-profile arrangement tucks the horn bells upward instead of letting them hang below the bracket.

Designed for most full-size pickups and SUVs. Verify your vehicle's available space.
