The Kleinn Model JK 220 Bolt-on Air Horn Kit is designed specifically for Jeep Wrangler JK models from 2007 to 2016, providing a powerful and attention-grabbing air horn system. This comprehensive kit includes all necessary components for a complete installation, ensuring a robust and reliable addition to your vehicle.
The primary function of the Kleinn Model JK 220 is to provide a loud and distinctive air horn sound for your Jeep Wrangler JK. Unlike standard vehicle horns, air horns produce a much higher decibel output, making them ideal for signaling in various situations, from off-road adventures to urban driving where increased audibility is desired for safety. The system operates by using compressed air to vibrate a diaphragm, producing the characteristic air horn sound. The kit is designed for a bolt-on installation, meaning it integrates directly with existing vehicle structures, minimizing the need for extensive modifications. The dual trumpet design ensures a rich and full sound.
The kit includes a Kleinn model #220 Dual trumpet air horn, which is the core component responsible for sound production. The installation wiring and connector kit ensures proper electrical integration with the vehicle's power system. Vehicle-specific mounting hardware, including a JEEPKIT mounting bracket and three backing plates, is provided to secure the horn assembly to the horizontal beam above the rear differential. This bracket is engineered to fit the Jeep Wrangler JK chassis precisely. The kit also comes with a 12-foot length of air tubing, allowing for flexible routing from the air source (not included in this specific manual, but implied to be part of a larger system like the JK-OBA) to the horn solenoids. A horn button is included for activation.
The mounting hardware for the Jeep Kit bracket and tank includes:
The air horn itself features two solenoids, which control the airflow to each trumpet. Small pieces of air line (8-12 inches) connect these solenoids to a "T" compression fitting, which then connects to the main air supply line. Electrical connections for the solenoids involve a "Y" connection using supplied black and purple wires, blue butt connectors, and red female bullet connectors. The system requires a 12V+ power source, which is typically connected via a fuse.
The Kleinn Model JK 220 is designed for straightforward operation. Once installed, the air horn is activated by pressing the included horn button, which sends an electrical signal to the solenoids, opening them to allow compressed air to flow through the trumpets. The bolt-on design ensures that the horn is securely mounted and positioned to deliver maximum sound output without interfering with other vehicle components. The vehicle-specific bracket clamps around the horizontal beam above the rear differential, a robust location that can withstand the vibrations and forces associated with off-road driving. The ability to remove the trumpets during installation simplifies the mounting process, allowing for easier access to the mounting hardware and wiring.
Maintenance for the Kleinn Model JK 220 primarily involves ensuring secure connections and proper functioning of the air and electrical lines. The manual emphasizes the importance of securing the airline to the "T" fitting and the wiring to prevent damage or dislodgement during vehicle operation. The ground wire should be connected to a paint-free metal surface to ensure a reliable electrical ground. Periodically checking the tightness of the Nyloc nuts on the mounting bracket is recommended to maintain the horn's secure position, especially after off-road use. The trumpets, once re-installed, should also be checked for tightness. The solenoids and air lines should be inspected for any signs of wear or leaks that could affect performance. The manufacturer provides a limited warranty of one year from the date of purchase, covering defects in workmanship and materials, which highlights the importance of proper installation and use for longevity. In case of issues, the manual directs users to contact their retailer or Kleinn directly for repairs or replacements.
