Though not exactly a big noise in the industry, Kleinn Air Horns is your number one source for excellent quality 1999-2017 exterior parts that give your GMC Sierra a powerful voice that makes everyone within hearing sit up and take notice. Kleinn’s air horns are made from tough, durable materials and engineered to transform the polite toot of your pickup’s stock horn into a tyrannosaurus roar that makes it clear who’s king of the road. Their 1999-2017 onboard air products crank out thunderous decibels, and even include remote controls that let you unleash a blast from a block away, whether it’s a signal, a prank on a friend, or a warning to a prowling thief not to mess with your car. These finely made air horns, kits, and controllers are 100% USA-made in Arizona, come with a 1-year limited warranty, and live up to the company’s motto – “Too Loud? Too Bad.”
