Built For Modified Rigs. Engineered To Dominate.
Standard horn kits assume your truck is straight off the factory floor—but your build is anything but stock. The Kleinn Automotive Accessories SDKIT17-230STL ABS Triple Train Horns and Onboard Air System is the ultimate, uncompromising solution for Ford Super Duty owners running oversized off-road tires, aggressive aftermarket bumpers, or heavy-duty behind-the-bumper winches.
When modifications take up valuable under-chassis real estate, this premium system saves the day. By utilizing vehicle-specific, powder-coated steel brackets, it intelligently reclaims the factory spare tire cavity to mount the legendary Kleinn Model 230 "The Beast" train horns. The air tank and compressor seamlessly tuck into the surrounding spaces without interfering with your aftermarket upgrades. The result? A completely hidden, high-performance stealth installation that protects your gear from road debris while delivering a true 100% bolt-on fit—meaning absolutely zero cutting, drilling, or welding on your truck's frame.
The Ultimate Onboard Air Command Center
Don't settle for basic horn kits that only make noise—this system transforms your rig into a fully functional, mobile pneumatic powerhouse. At the heart of this heavy-hitting package is a genuine Kleinn heavy-duty, 100% duty-cycle waterproof air compressor paired with a high-capacity air tank.
This creates an incredibly versatile onboard air station engineered for real-world utility. Whether you need to air up large off-road trail tires after a weekend of wheeling, manage air suspension helper bags on the fly, or run pneumatic air tools right from your truck bed, this system delivers instant, reliable high-pressure air on demand. Every chassis-specific bracket, high-pressure airline, and premium hardware component is precision-engineered to tuck completely out of sight, providing clean, stealthy integration while offering maximum defense against harsh road debris, mud, and the elements.
Professional-Grade Durability, Stealth Bolt-on Design
You shouldn't have to sacrifice your truck's clean factory lines to get massive acoustic power. This complete onboard air and train horn system delivers the ultimate combination of high-output performance and a discreet, factory-style aesthetic.
Engineered specifically to survive the most punishing conditions, every component is strategically tucked away to maintain your rig's clean look while keeping the hardware safe from mud, water, and road debris. It is the perfect, low-profile upgrade for serious custom truck builds that demand maximum dependability without the cluttered look of universal kits.
Highlights for SDKIT17-230STL: Ford super-duty 2017-2026

These vehicle-specific, heavy-duty steel mounting plates feature a durable black powder-coated finish and bolt directly into existing factory frame holes, providing a rock-solid, custom-fit foundation engineered specifically for proprietary, genuine Kleinn components.
- Strategic Multi-Zone Space Allocation: Brackets locate the air tank along the crossmember in front of the spare tire area, tuck the compressor safely on the passenger side inner frame rail, and position the massive horns directly in the empty factory spare tire pocket.
