Equip your truck with the Kleinn spare tire location onboard air system, engineered specifically for owners of lifted trucks running oversized tires who no longer utilize their factory spare tire mount. This premium heavy-duty kit provides a reliable, high-volume air source directly on your chassis, allowing you to easily inflate large tires, power air tools, operate air suspension bags, or tackle demanding off-road challenges. The entire high-performance package mounts securely beneath the truck bed using a custom-designed bracket that is fully supported by the original equipment manufacturer factory spare tire winch. This innovative setup ensures a true tool-free installation that requires zero bolts and absolutely no cutting, welding, or drilling, making it an easy fit for most full-size trucks. The heart of this high-performance system features an industry-exclusive, heavy-duty 100 percent duty cycle waterproof air compressor paired with a three-gallon air tank, delivering a powerful 200 PSI maximum pneumatic foundation. For ultimate utility, the package arrives in one box complete with a high-pressure tire inflation kit, all necessary high-grade air lines, wiring, and vehicle-specific hardware. It also includes a 160 PSI air pressure gauge featuring a custom dash-mounting plate and an integrated switch to illuminate the gauge for effortless monitoring during night use. Designed as a versatile standalone pneumatic station, this system allows you to easily expand your setup by adding any Kleinn air horns, or you can step up to a complete acoustic package by pairing it with the USTL-230 composite train horn kit or the USTL-734 steel train horn kit. Built to endure the toughest environments, this complete system provides the ideal balance of clever, hidden original equipment manufacturer style mounting and high-output pneumatic performance that serious custom truck builds count on.
