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.
