Four wide-flare bells that mount individually, so they can be spread out wherever there is room. The deep, layered tone people turn around for, not an electronic imitation.
Every kit ships with its own compressor and tank. It fills itself between honks, and the same air supply can top off tires or run small air tools.
Air line, wiring kit with fuses, fittings, mounting hardware, the electric air valve, an air line cutter, instructions, and earplugs.
One recording of the Shocker XL at full pressure. No editing.
Phone speakers undersell it. Earplugs ship in the box for a reason.
Same four-trumpet Shocker XL in every kit, and all six air up tires and run air tools. What changes is how long you can honk, how fast it refills, and how hard the compressor can keep working.

Duty cycle is about heat, not a timer. The compressor runs whenever it needs to. Work it hard enough and it gets hot, and a thermal overload switch shuts it off until it cools.
A 25 or 30 percent compressor reaches that point sooner, so a long job can pause partway through. A 100 percent compressor keeps going much longer before heat stops it, which is what matters if you are airing up a set of tires or running an air tool.
On the 127H and 228H the compressor comes pre-mounted to the tank as one assembly. That is the simplest install we sell and the lowest price. Taking it apart voids the warranty.
From the 232 up, the tank and the compressor are separate pieces you can mount apart to fit the space you have, and the compressor itself is heavier duty. That is why the 232 costs more than the 228H, even though the two hold the same air and honk just as long.
Stealth Black disappears under the truck. White shows the horns off. Same four trumpets, same air system, same sound.

HornBlasters does not publish fill figures for the 8-gallon tank. These are calculated from the measured 5-gallon dual-compressor times, scaled by volume.
Trucks, cars, semis. This is the kit we recommend most for cars, because all of the components can be spread out and mounted individually: horns in the front or rear bumper, behind the grille, or one in each wheel well, with the air system in the cargo area or trunk. Same horn on every one of these. Swipe through.
Hundreds more builds across trucks, vans, semis, boats and more. Search it for your own year, make and model.
The Shocker XL train horns are backed by our lifetime manufacturer’s defect warranty. Every other component in the kit is backed by our 2-year manufacturer’s defect warranty.
We offer a 30-day satisfaction replacement or refund guarantee on all purchases, except where otherwise noted in the product listing.
Merchandise may be returned within 30 days from the shipment arrival date for a refund. A Returned Merchandise Authorization (RMA) number is required for all returns, and a 15% restocking fee may apply. Please report any order discrepancy within 7 days of the invoice date.
Physical damage to any product voids warranty coverage. This includes improper handling and any damage sustained by irregular usage.
On the 127H and 228H kits, detaching the compressor from the tank voids your warranty. If you need a solution where the compressor is detached from the tank, look at our 232 and higher models.
