2011 Volvo XC90 Train Horn and Air Horn Kits for Trucks

Train Horn Kits

Are you tired of your ride’s weak, tinny factory horn? Consider replacing the OE electric horns with a high-power, pneumatic train horn featuring immense volume and an attractive tone! 

Train horns require several components for operation, including an onboard air compressor, air tank, fittings, air lines, and the horns themselves! These kits include multiple horns that produce varying tones, resulting in a loud, piercing blast that can be heard both near and far! Whether you’re warning other drivers of imminent danger or blaring your horn to avoid a collision, a train horn from RealTruck ensures your message is heard loud and clear! 

At RealTruck, we offer a wide selection of train and air horn components, including: 

• Air Tanks: The component stores compressed air that’s later dispersed when you actuate the horn. Alternatively, you can add a valve and line to fill up tires or blow off debris! 

• Air Compressor: This product compresses and forces air into the air tank. We recommend an onboard compressor with every train horn system. 

• Universal Kits: If you don’t mind a bit of fab work, we offer universal train horn kits that include everything necessary to install, plumb, and wire up your train horns! 

• Bolt-On Kits: If custom work isn’t your forte, we offer several vehicle-specific kits for a simple, bolt-on installation. 

• Dual, Triple, and Quad-Horn Setups: Whether you’re looking for a simple dual-horn setup or an ear-piercing quad-horn kit, we carry it all!

Air Horn FAQs

Q: Are air horns legal? 

A: While no state prohibits the installation or ownership of train horns, that doesn’t mean it’s always legal to use them! Some states, including California and those that require annual inspections, prohibit operating train horns on public roads. 

Q: Is there a volume limit on car horns? 

A: Yes! The maximum decibel limit for car horns in the United States is between 100 and 110. 

Q: How difficult is installing a train horn system? 

A: Train horn installation difficulty varies by product and vehicle; however, we offer several bolt-on kits that require no fab work! In all cases, wiring and air hose plumbing is required.
