At the heart of every Kleinn onboard air system is a 100% duty-cycle, submersible waterproof air compressor engineered for extreme reliability, fast recovery, and maximum airflow. The high-output compressor feeds a high-capacity, anti-corrosion inner-coated steel air tank built to withstand harsh under-vehicle conditions while delivering consistent pressure and long-term durability for your rig.
When activated, Kleinn train horn systems deliver a true locomotive-style blast engineered for maximum airflow and aggressive output. Whether equipped with ABS (230) or stainless steel (730) horns, each system is tuned to produce a serious road-clearing presence and the kind of attention-commanding performance professional truck builds demand.
Kleinn systems don’t just outperform the competition—they redefine the standard. For more than 15 years, Kleinn has dominated by providing the most powerful onboard air systems and unrivaled locomotive volume available. As the only manufacturer to offer true, vehicle-specific bolt-on kits that preserve your OEM spare tire, Kleinn systems provide the perfect fusion of massive airflow and the real-world utility required for tire inflation, air lockers, and pneumatic tools.
Every Kleinn direct-fit train horn and onboard compressed air system starts at the Kleinn Automotive Accessories engineering facility in Tucson, Arizona. Our team designs and builds precision-fit, powder-coated steel brackets and pairs them with premium hardware defining what a "true" direct-fit kit should be.
These chassis-specific brackets bolt directly to factory mounting points, delivering a flawless, no-drill OEM-style installation that eliminates the guesswork and frustration of universal kits. By utilizing heavy-duty, laser-cut steel, we ensure each component is securely anchored to the vehicle, providing a stable foundation that can withstand extreme vibration and harsh off-road environments.
Ditch the DIY guesswork. Experience a 100% bolt-on transformation that pairs OEM-Style finish with the aggressive performance of our signature train horn blast and compressed air system. Engineered for a perfect fit and maximum decibel output, this is professional grade power designed to dominate the road.
Kleinn systems are engineered for long-term reliability, heavy-duty performance, and minimal maintenance. Every component is built to withstand harsh under-vehicle conditions while maintaining consistent air pressure and dependable output. Our onboard air systems don’t just survive the elements—they deliver professional-grade power exactly when you need it.
To maximize this utility, each complete system includes the Kleinn INF-1 Tire Inflation Kit and the (1302) Air Coupler Relocation Kit. This powerful combination transforms your vehicle into a convenient mobile air service station, providing the pneumatic muscle required for everything from rapid trail-side maintenance to daily heavy-duty utility.
Whether you’re commanding the road with a massive blast, airing up truck tires, or engaging pneumatic accessories, this system is engineered to stay strong and stay loud. The "Demon" bolt-on models ending in -734 enjoy an extended 2-year warranty on both the compressor and horn assembly. Don’t just hit the trail—dominate it with the peace of mind that comes with professional-grade engineering.
Choosing the right system for your truck depends on your demand for air power and volume. While all options are 100% bolt-on, Kleinn systems are categorized into three distinct performance tiers:

Maximize your horn's potential by upgrading the airflow. These kits bypass standard restrictions to deliver instant air directly to each horn.
Engineered specifically for -230 Beast Series systems, the 6885 BlastMaster™ shatters the limitation of standard 1/4" line. By feeding high-velocity air through a massive 1/2" primary line directly to a high-flow manifold, this kit floods each solenoid with maximum air volume. The result is a devastating increase in output and a sharper, perfectly synchronized tri-tone blast that hits with absolute authority.
Engineered for our flagship -734 Demon Series, the 6890 Ultra BlastMaster™ unleashes the dominance of the legendary 730 Demon Stainless Steel Horns. This kit completely replaces standard plumbing with a specialized high-volume manifold and 1/2" Max-Flow lines. By equipping each horn driver with its own dedicated solenoid, the 6890 upgrade ensures synchronized engagement and peak pressure for every blast.
