Kleinn FSD23-734 Onboard Air System with Model 730 Demon Horns for 2023-2026 Ford F-250/F-350

Fits 2023-2026 Ford F-250 and F-350 Super Duty (All Trims).

The Kleinn FSD23-734 is a vehicle-specific onboard air and train horn system designed for a 100% direct bolt-on installation. Engineered and manufactured in the USA, this kit features chassis-specific, powder-coated steel mounting brackets that attach directly to factory holes, requiring no drilling, cutting, or welding. The high-performance layout is designed to completely retain your factory spare tire for a clean, stealthy under-truck setup.

The system is anchored by the triple-trumpet Model 730 Demon train horns, constructed from spun steel with a durable black finish to produce a 157.9 decibel output. Air supply is managed by the Model 6450RC waterproof high-output compressor, which delivers 150 PSI at a 100% duty cycle. Paired with a heavy-duty 3-gallon air tank, this setup functions as a complete onboard air station capable of inflating tires up to 37 inches, powering pneumatic tools, or supplying air suspension components.
