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.\u003c\/p\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/71aaf76fa76a79979d2455d499a65b3a.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/4a9c2621e84e07a49b662ea4137c265d.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e","brand":"Kleinn Air Horns","offers":[{"title":"Default Title","offer_id":44490659365071,"sku":"KLE401","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/4164\/7055\/files\/Kleinn-Chrome-Roof-Mount-Dual-Horn-135In115In-Chro-1758342465.webp?v=1758342466","url":"https:\/\/www.cimotorsports.com\/products\/kleinn-chrome-roof-mount-dual-horn-13-5in-11-5in-chrome-plated-spun-copper","provider":"CI Motorsports","version":"1.0","type":"link"}
