Now is the perfect time to upgrade your vehicle's voice on the road with a state-of-the-art horn kit. Advances in technology have significantly improved the quality of components and broadened the range of kits available, ensuring unparalleled quality. At HornBlasters, we offer an unmatched selection of horn kits, suitable for vehicles of all types, including trucks, cars, motorcycles, SEMIs, and boats, as well as anything powered by 12-volt, 24-volt, or 110-volt electrical system. We understand the challenge of selecting the perfect kit from our vast array, but we're here to guide you to the ideal choice that meets your vehicle's needs and fits your budget.


  • Listen to the Sound Samples - Every horn and horn kit we offer features Sound Samples on the product page, allowing you to hear the exact tone you're investing in. Preference for a higher-pitched tone? Consider an air horn. For deeper resonance, a train horn is your go-to choice. Listening beforehand ensures your satisfaction with the horn's sound.
  • Choosing the Right Onboard Air System - Your use case, whether for inflating tires, enhancing air suspension, or simply for the horn, is key to choosing the right air tank and compressor. A fast-fill compressor is ideal for horn-focused users, but for those who demand a system capable of handling a variety of pneumatic tasks, a constant duty compressor is the recommended choice for its versatility and reliability.
  • How much air do you need? The capacity of your air tank is essential, as it impacts the duration of horn blasts and the availability of air for additional functionalities like inflating tires or supporting air suspension systems. On average, each gallon of air in the tank equates to about two seconds of horn operation. For instance, a 2-gallon air tank can sustain a horn blast for about 4 seconds, while a 5-gallon tank can last about 10 seconds. It's important to note that bigger train horns will deplete air more quickly.
  • Make sure everything is going to fit - The reality is, that not every vehicle has the space to house massive train horns or an extensive 8-gallon air system. Depending on the kit, some of our systems are suitable for exposure to the elements, while others require a clean and moisture-free area. We recommend planning your installation out in advance and checking the dimensions listed under the specifications tab on our product pages to ensure a seamless fit.
  • Make sure you buy a kit with high-quality components - By considering a HornBlasters kit, you're already focusing on quality. Should you explore other options, remember the importance of high-quality components. Our kits predominantly feature ½ inch air lines for optimal airflow and louder sound output, unlike kits with smaller air lines. Avoid non-DOT approved parts, and remember, if a deal seems too good to be true, it likely is. Quality doesn't come cheap, and there are no shortcuts to achieving 150 dB with a $60 kit.
  • Give us a call - Unsure about the best kit for your needs? Our team of train horn enthusiasts is eager to help, equipped with the technical know-how from personal experience with installation, usage, and maintenance. Reach out via phone, email, or chat on our site for personalized advice. Toll-Free: +1 877-209-8179


At HornBlasters, we understand the thrill of making your presence known on the road, whether you're aiming to rival the roar of a locomotive or simply upgrading from a less impressive factory horn. Our selection spans a broad spectrum, offering options from the budget-friendly sub-$100 range to premium choices exceeding $2000, with countless configurations in between to suit every enthusiast's needs and budget.

Navigating the world of train and air horns can be daunting for newcomers, which is why we've highlighted three of our top-selling train horn kits and air horn kits below. Each selection represents a variety of price points, ensuring you'll find something that resonates with your style and wallet.


Ever wondered about the distinction between a "train horn" and an "air horn"? The difference lies in their sound profiles: train horns are designed to mimic the deep, resonant tones of a locomotive, offering an unmistakable and commanding presence. On the other hand, air horns cover a spectrum of higher pitches and distinctive sounds, catering to a range of personal tastes and vehicle applications.

To give you a clearer picture, let's dive into some examples from our varied collection of popular air horns, ensuring you make an informed decision that amplifies your vehicle's character perfectly.


Renowned for their distinctively higher pitch, air horns offer an alternative to the deeper, more resonant train horns. Not only do they tend to use a smaller air system, but many of our air horn kits come ready-to-install with pre-plumbed and pre-wired systems, simplifying the setup process significantly compared to their larger train horn counterparts. Whether you're venturing into the world of aftermarket horns for the first time or working within a specific budget, our air horn selections provide an excellent starting point.

The HornBlasters Safety 232 Air Horn Kit is a standout choice for its versatile Safety Air Horn, acclaimed for its compatibility as the perfect addition alongside existing train horn setups. This particular horn is celebrated for its fire truck-like urgency, making it a preferred option for those looking to enhance their vehicle's audible impact without compromising on clarity and strength.

The unmistakable roar of a train horn is unparalleled in both volume and depth. For those who aim to maximize their vehicle's presence, a train horn kit is the ultimate choice. Train horns distinguish themselves by delivering a deeper, more resonant blast that cuts through ambient noise with ease. Due to their robust sound output, train horns typically require larger air systems, which is why we pair them with our most durable onboard air compressor systems. These heavy-duty systems are not only engineered to power your train horn but are also versatile enough to handle a wide range of pneumatic applications, making them an essential addition for enthusiasts seeking the most impactful sound experience.
