Kleinn 17-26 Ford F-250/ F-350 Onboard Air System w/ Model 730 Horns Spare Tire Location

The Kleinn SDKIT17-734STL train horn and onboard air system is the perfect solution for Ford Super Duty owners who have lifted their truck and are running oversized tires, installed an aftermarket bumper, or added a behind-the-bumper winch. Designed specifically for modified vehicles where traditional mounting space is limited, this premium kit features a custom-engineered bracket that bolts directly into the location where the factory spare tire would normally be housed. The system includes the legendary, earth-shaking blast of our Demon model 730 steel triple train horns, delivering unmatched volume and performance. Providing the pneumatic power is a heavy-duty, 100 percent duty-cycle waterproof air compressor paired with a generous three-gallon air tank, creating a versatile onboard air station. The comprehensive kit comes complete with every single part needed for a simple, true 100 percent bolt-on installation using existing factory holes with absolutely no cutting, welding, or drilling required. For enthusiasts looking to maximize their sonic output, the entire setup can be upgraded to deliver a 40 percent louder blast by adding the part number 6890 BlastMaster valve upgrade kit. Built to endure the toughest environments, this package provides the ideal balance of clever, out-of-the-way mounting and high-output performance that serious custom truck builds count on.

LOUIS HERNANDEZ – June 10, 2026
This air system is powerful and the 730 horns are LOUD. exactly what I wanted. Install on the F-350 took a couple hours and the kit is complete.

Alexis Verduzco – June 17, 2026
Installed the Kleinn onboard air system with the 730 horns on my F-350 and it’s been the most entertaining purchase I’ve ever made. The air pressure builds quickly and the horn is absolutely commanding, nobody cuts me off anymore. Beyond the horns, having onboard air for trail tire inflation has been incredibly useful. The system mounted cleanly in the engine bay and the install was well documented. Kleinn clearly builds these for real trucks. Couldn’t be happier.

Added this Kleinn onboard air system with 730 horns to my F-350 mainly for airing up tires after off-road trips, but the horns are a serious bonus. Compressor keeps up well even filling larger tires from low pressure. Horn volume is startlingly loud in the best way, definitely gets attention on the highway when needed. Wiring diagram included made the install manageable in an afternoon in my garage. Everything is mounted cleanly out of the way under the bed. Great dual-purpose system for a work truck.
