Model SDKIT17-230STL: Spare Tire Location Onboard Air & Triple Train Horn System

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

  • Custom Mounting Brackets: Direct-Fit No-Drill Infrastructure. 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.
  • Model 230 "The Beast" Triple ABS Train Horns: Three high-impact ABS plastic trumpets (18.5”, 16.5”, 14.5”) paired with heavy-duty zinc alloy bases and a high-flow VX6003 brass solenoid. Pre-fitted with a dedicated 1/4" airline to individual trumpets for a brutal multi-tone locomotive roar.
  • Model 6350RC Waterproof Air Compressor: Industry-exclusive fully sealed pump delivering up to 150 PSI with a 100% duty-cycle, engineered to operate flawlessly in harsh, moisture-heavy under-truck environments.
  • Model 6351RT 3-Gallon Air Tank: Specialized heavy-gauge steel multi-port reservoir treated with an internal Cortec anti-corrosion coating to eliminate rust and protect downstream components.
  • Premium INF-1 Tire Inflation Station: Includes a pro-grade inflation setup featuring a 24' heavy-duty air hose with pre-attached quick-connect couplers, a custom analog glow-gauge inflator, a secure clip-lock chuck, and an integrated pressure-release button.
  • 1302 Quick-Connect Relocation Architecture: Fully equipped with a dedicated bumper/hitch mounting bracket layout, 12 ft of specialized high-pressure airline, and premium adapter fittings designed to position the inflation port cleanly under your bumper or next to your trailer hitch receiver.
  • Installation Pack: 1/4" OD high-pressure airline, automated pressure switch, high-pressure tank fittings, wiring kit, mounting hardware, and horn button.

Unleash the Beast with the Model 6885 BlastMaster Upgrade Kit. By replacing standard routing with heavy-duty 1/2" lines and dedicated high-flow brass solenoids, this upgrade maximizes tank airflow to deliver an earth-shaking 30% increase in sonic output.
