Kleinn Chrome Roof Mount Dual Horn/ 13.5In/11.5In - Chrome-Plated Spun Copper

Equip your truck with the Kleinn 401 direct-fit dual chrome-plated roof-mount air horn system, featuring two all-metal trumpets measuring 15 inches and 13 inches in length to create a deafening blast of over-the-road fury. Engineered for universal semi-truck and commercial vehicle applications, this premium roof-mounted dual horn configuration delivers an authentic big-rig tone, producing a massive 152.1 decibels of sound at 150 PSI. Designed for custom external mounting, this high-performance horn kit requires a pressurized onboard air system, a manual hand-pull air valve (Model 310 or 311), or an electronic solenoid valve to operate. For a proper and leak-free setup, the installation requires a Model 330 Roof Mount Air Horn Fittings Kit, providing the ultimate balance of glistening chrome style and serious acoustic presence that heavy-duty custom truck builds count on.
