Equip your truck with the Kleinn 411 direct-fit single chrome-plated roof-mount air horn system, featuring a single premium all-metal trumpet measuring 25 inches in length with an oversized bell end to deliver the ultimate big-rig sound.

For a proper, leak-free setup right out of the box, the installation requires a Model 330 Roof Mount Air Horn Fittings Kit, providing the ideal balance of gleaming chrome style and serious acoustic presence that serious custom truck builds count on. 22-3/8" Stainless Steel roof mount round truck horn (no solenoid or manual pull valve included).
