The Kleinn Universal Spare Tire Location Train Horn Kit is designed for truck owners who want maximum train horn performance without sacrificing space or dealing with complex installs. It delivers a powerful locomotive blast while utilizing an otherwise unused mounting location.
Built around a custom-engineered mounting bracket, the entire system—horns, compressor, and air tank—mounts securely where the spare tire normally sits. This makes it ideal for lifted trucks or vehicles running oversized tires where the spare tire location is no longer used.
Additional features include a 3-gallon air tank, a high-output waterproof compressor (up to 200 PSI, 100% duty cycle on higher-end variants), and either Beast (Model 230) or Demon (Model 730) horn configurations depending on the kit. This setup provides strong, sustained blasts and fast recovery times.
Engineered with universal fitment, the system works on most full-size trucks and SUVs, especially those with modified suspension setups.
Installation is typically a true bolt-on process, using the OEM spare tire hoist to raise and secure the bracket—eliminating the need for custom fabrication.
Whether you're upgrading for off-road builds, towing safety, or maximum road presence, this kit delivers a clean install with serious performance. Now Available at LEER!
