The Kleinn Add-On JK/JL/JKU Horn Kits are designed for Jeep owners who want serious horn performance without replacing their entire air system. These kits bolt directly onto your vehicle and integrate with an existing onboard air setup, making them one of the easiest ways to upgrade sound output.
Built around Model 220 dual train horns, these systems deliver powerful, attention-grabbing output that far exceeds factory horns. The train horn variants produce a deep, aggressive tone, while dual air horn versions offer a sharper, more compact sound profile.
Additional features include vehicle-specific mounting brackets, pre-configured wiring, and compatibility with Kleinn JL-JK onboard air systems or any system with at least a 1-gallon tank.
Engineered specifically for Jeep Wrangler platforms (JK, JKU, JL, JLU), these kits install cleanly without interfering with other components.
Installation is typically a true bolt-on process, requiring no drilling or cutting when using factory mounting points.
Whether you're upgrading for trail safety, off-road visibility, or just to be heard, this add-on kit delivers a huge performance boost. Now Available at LEER!
