Vehicle 1971 Volkswagen Super Beetle

Zach's 1971 Volkswagen Super Beetle already turns heads with its custom roof rack and patina finish, but the Shocker XL Train Horns take this build to another level. Mounted up top, the horns broadcast a true locomotive chord that keeps this small car safe and impossible to ignore.

The Shocker XL horns-only kit (part number AH-S4) supplies the four fiberglass-reinforced ABS bells, 1/2-inch stainless steel electric valve, airline, and fittings. Zach paired the horns with a compact 150 PSI onboard air system tucked under the hood, feeding the bells via a 110 PSI restart switch so every blast is consistent. Because the kit is modular, each bell can be positioned for the best clearance on the rack.

The different bell lengths—19.5, 16.25, 14.75, and 12.75 inches—deliver the rich four-note chord that defines the Shocker XL. Zach aimed the bells forward to cut through traffic noise while keeping the rack usable for luggage, blending safety with style on this classic Super Beetle.

Train Horn FAQ

No, the Shocker XL Train Horn is a standalone horn and does not include an air tank or compressor. You will need to pair it with an onboard air system to power the horn properly.

The Shocker XL Train Horn is made up of individual bells that can be mounted separately, which is ideal for a compact classic like the Super Beetle. Mounting the horns on the roof rack keeps them clear of the engine bay and gives them a clear path to project sound.

The Shocker XL horn-only kit provides the four fiberglass-reinforced ABS bells, a 1/2-inch electric valve, airline, and fittings. You will still need an appropriate air tank and compressor to complete the system on your car.

The Shocker XL Train Horn is one of HornBlasters' loudest horns and is tuned to sound like a real locomotive. Even on a small car like a 1971 Super Beetle, it produces a powerful four-note train chord that stands out in traffic and at shows.

Yes. Because each bell of the Shocker XL Train Horn is separate, you can mount them along the pan, behind bumpers, or on custom brackets as long as they are secure and have room to project sound. Just make sure they clear suspension travel and steering components.
