Utilizing chassis-specific, USA-made powder-coated steel mounting brackets that attach directly to factory holes, this high-performance kit completely retains your factory spare tire while requiring absolutely no drilling, cutting, or welding. The system features the legendary, triple-trumpet Model 730 spun steel black-finish Demon train horns, unleashing a spine-tingling 157.9 decibels of earth-shaking blast. Powering this setup is an industry-exclusive, 150 PSI 100 percent duty cycle Model 6450RC waterproof high-output air compressor paired with a heavy-duty 3-gallon air tank, creating a versatile onboard air station capable of inflating up to 37-inch tires, powering air tools, or supplying air suspension setups. Every premium component, high-pressure line, and wire harness is precision-engineered for a factory-clean, stealthy under-truck setup, backed by a comprehensive warranty to ensure the ultimate balance of original equipment manufacturer style mounting and high-output performance.
