Kleinn Horns Accessory Horns: Built to Be Heard

When the factory horn on your truck, SUV, or off-road rig simply isn't cutting it, Kleinn Horns delivers a genuine step up in presence and safety. As a U.S.-based manufacturer focused exclusively on pneumatic and electronic sound systems, Kleinn has built a reputation around one core promise: maximum volume, zero compromise. Their Accessory Horn lineup channels that same engineering DNA into bolt-on upgrades that transform how any vehicle commands attention on the road.

What Sets Kleinn Apart in the Accessory Horn Category

Kleinn is a U.S. manufacturer specializing in premium air horns and complete air horn systems, with a sharp focus on creating solutions that require no cutting, drilling, or welding. That bolt-on philosophy extends directly to their accessory horn products, making them approachable for everyday drivers and hardcore enthusiasts alike.

From compact dual air horns and direct drive kits to massive triple and quad train horns, Kleinn's lineup covers every style and decibel level — with options in chrome-plated ABS, stainless steel, and roof-mount configurations. Whether you're looking for a clean, understated upgrade or a setup that replicates the blast of a locomotive, Kleinn offers a configuration to match.

Direct Drive Horn Kits: The Accessible Entry Point

Kleinn's Direct Drive air horn sets are a simple upgrade for a factory horn, coming as a complete kit ready for an easy install with a direct drive compressor, mounting hardware, and relay — featuring chrome-plated metal trumpets that will not crack or break like lesser products with thin plastic trumpets. One standout example is the Model 101, a dual truck horn featuring two black XCR2.0 trumpets at 7.5" and 10" in length. It's the same horn featured in Kleinn's Jeep Trailblaster™ kits — so popular it's offered as a standalone.

Upgrade Kits: More Air, More Sound

Kleinn also offers accessory horn upgrade kits for those who want to push their existing systems further. The Ultra BlastMaster™ Air Valve Upgrade is designed for Model 730 Demon™ train horns, while the Vortex™ upgrade kits are engineered around the principle that more air volume delivered to an air horn translates directly to more volume. These kits are ideal for enthusiasts who already own a Kleinn horn assembly and want to maximize its output without replacing the entire system.

Engineered for Durability and Backed by Warranty

Kleinn stands behind the craftsmanship and materials of their products with a comprehensive one-year limited warranty extended to the original purchaser, covering defects in workmanship and materials for one year from the date of purchase. Select high-performance products even qualify for an exclusive extended two-year warranty, reflecting Kleinn's confidence in those products' durability and performance.

For truck owners, off-road builds, or anyone tired of a timid factory horn, Kleinn's accessory horns deliver the authentic, commanding sound that gets attention — whether on the highway, the trail, or anywhere in between.
