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\u003cul\u003e\n\u003cli\u003e330 Fitting Pack required if not replacing an existing roof mount horn\u003c\/li\u003e\n\u003cli\u003eManual Hand Pull Air Valve 310 or 311 \/ Solenoid Required\u003c\/li\u003e\n\u003cli\u003eChrome-Plated Stainless Steel Construction\u003c\/li\u003e\n\u003cli\u003eDimensions (in): 15.75 x 7.5 x 4.25\u003c\/li\u003e\n\u003cli\u003eTwo Trumpets 15.5\"\/13.25\" Lengths\u003c\/li\u003e\n\u003cli\u003eOutput (dB) @ 150 psi 152.1\u003c\/li\u003e\n\u003cli\u003e1\/4\" Airline Input\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kleinn Air Horns","offers":[{"title":"Default Title","offer_id":45833873653913,"sku":"KLE401","price":119.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/1227\/4585\/files\/7eb36d2365e9e625f7e24d65f2ba64cdL.jpg?v=1761572470","url":"https:\/\/battlebornoffroad.com\/products\/kleinn-chrome-roof-mount-dual-horn-13-5in-11-5in-chrome-plated-spun-copper","provider":"Battle Born Offroad","version":"1.0","type":"link"}
