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\u003cp\u003eKleinn 401 - Roof Mount Dual Chrome Air Horn (Manual Pull Valve or Solenoid, SKU# 330 not included)\u003c\/p\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\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Kleinn Air Horns","offers":[{"title":"Default Title","offer_id":47854693122199,"sku":"kle401","price":116.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0497\/9697\/2695\/files\/ca0702f2e511290110d7c9201423c742.jpg?v=1780071522","url":"https:\/\/nlpperformance.com\/en-ca\/products\/kleinn-chrome-roof-mount-dual-horn-13-5in-11-5in-chrome-plated-spun-copper","provider":"Next Level Performance","version":"1.0","type":"link"}
