HornBlasters Rage 4-Chime 3-Liter Review

The HornBlasters Rage 4-Chime 3-Liter Air Horn Kit is a compact, all-in-one 12-volt setup for buyers who want a complete four-chime system without stepping up to a much larger air reserve. Its appeal is not that it does everything a five-gallon system can do. It is that the horns, air valve, compressor, tank, wiring pieces, and basic installation hardware are supplied as one matched package.

That makes the Rage worth a close look for a vehicle with a protected mounting location and a buyer who values a pre-plumbed, pre-wired air source. The trade-off is important: the 3-liter tank and 120-PSI system are intended for a compact kit, not prolonged horn blasts or a multi-purpose onboard-air setup.

What comes in the Rage 4-Chime kit

HornBlasters lists the Rage package as its HK-4CHIME-M3 kit. The four-chime horn has a pre-installed 1/4-inch electric air valve. The included AC-M3 air-source assembly combines the 3-liter tank and compressor and arrives pre-plumbed and pre-wired, with an attached pressure gauge and pressure switch.

• Four-chime HornBlasters air horn with pre-installed 1/4-inch air valve
• AC-M3 3-liter compressor-and-tank combination
• 10 feet of 1/4-inch air line
• 22 feet each of 10-gauge red wire and 18-gauge blue wire
• Inline fuse holder, toggle switch, relay, electrical terminals, fittings, and mounting hardware
• Instructions, an air-line cutter, and earplugs

That list matters because a complete kit reduces the number of decisions a first-time buyer must make. It does not remove the need to plan the mounting positions, route wiring carefully, and confirm that the supplied line lengths work for the specific vehicle.

Air system, capacity, and recovery

The Rage uses a 3-liter air source with a 120-PSI operating pressure and a 90-PSI restart point. HornBlasters specifies a 12-volt system with maximum current draw of 18 amps. Its published fill figures are about two minutes from empty to 120 PSI and about 35 seconds from 90 to 120 PSI at 13.8 volts.

For the intended use, that is a practical compact-air-system balance. It is better suited to deliberate, short horn use than to repeated long blasts. Buyers who need a larger reserve for long-duration use, frequent recovery, air tools, or a separate air-suspension job should compare a larger onboard-air configuration rather than expecting this small tank to perform like one.

Horn size and fit considerations

According to the manufacturer, the horn assembly measures 13.5 inches long, 13.25 inches wide, and 4.25 inches high. The AC-M3 source assembly is listed at about 16.5 inches long, 4.9 inches wide, and 7.1 inches high. Those measurements make the Rage a more realistic candidate for a protected truck-bed box, interior compartment, or another dry mounting space than a large standalone-tank system, but clearances should be measured before ordering.

The dimensions are only part of the fit check. Leave room for the wiring run, air line, access to the 1/8-inch NPT drain port, and a path that does not expose the horn or air source to heat, moving parts, or debris. A clean mounting plan is more valuable than trying to force a compact kit into an unsuitable space.

Installation notes that matter

The Rage has a real convenience advantage because the source assembly is already plumbed and wired. The manufacturer still gives two constraints that should be treated as non-negotiable: the tank-mounted compressor is not fully sealed, and the assembly should be mounted upright in an enclosed area away from moisture, dirt, and debris. HornBlasters also says detaching the compressor from the tank voids the kit warranty.

Who the Rage fits best

The Rage is a sensible fit for a buyer who wants a four-chime horn, prefers a single matched package, and has a dry upright location for the air source. The supplied wiring and air-line pieces also make it a straightforward option for someone who wants fewer component decisions than a pieced-together setup.

It is not the right choice for a buyer who needs a large air reserve, plans to relocate the compressor away from the tank, or cannot provide a protected mounting location. In those cases, the practical answer is a different kit architecture—not an improvised installation that works around the Rage’s stated requirements.

Verdict

The HornBlasters Rage 4-Chime 3-Liter Air Horn Kit stands out as a compact, complete four-chime option with a matched 12-volt air source and clear published package details. Its strongest case is a careful installation where its compact tank/compressor assembly can stay upright and protected. Its limitations are equally clear: 3 liters and 120 PSI are appropriate for short, intentional use, not the job of a much larger air system.
