Kleinn Onboard Air System & Model 730 Demon Triple Train Horn Kit for Ford (2011-16) F-250/F-350

This Kleinn Model 730 train horn and onboard air system is made for the 2011-2016 Ford F-250 and F-350 Super Duty. Chassis-specific brackets bolt to factory mounting points so the whole system lives under the truck.

You get Kleinn's 6450RC compressor (rated to 200 PSI, 100% duty cycle, submersible), an inner-coated steel air tank, and the stainless steel Model 730 Demon triple horns on 1/2" Max-Flow airline. Also in the box: the INF-1 tire inflator with a glow-in-the-dark gauge, 24' heavy-duty hose with quick-connect couplers, a storage bag, the 1302 coupler relocation kit with 12' of airline, a pressure switch, relay, wiring and loom, a horn button, fittings, mounting hardware and thread sealant.

Plenty of these trucks are still pulling fifth wheels and goosenecks every weekend. Adding onboard air built around the 6450RC compressor means you can check and fill tires at the campground or on the shoulder, and the 730s handle the rest.

No drilling, cutting or welding, and the spare tire is retained. Fitment is confirmed for diesel trucks; if you have a 6.2L gas truck, contact us before ordering. The F-450 is not listed for this kit.

Covered by a 1-year limited warranty, and Kleinn lists extended 2-year coverage on the compressor and horn for 734 kits. The 6890 Ultra BlastMaster valve upgrade fits 734 systems.
