Methodology
This review aggregates publicly available information from manufacturer specifications, retailer listings, and verified user reviews. We do not perform hands-on testing. Last reviewed: October 25, 2026. Specs come first from Kleinn’s official Model 130 product page and its published spec table, cross-checked against the Kleinn Model 130-1 (black) listing, Kleinn’s sister compact horns (Models 102 and 141), Kleinn’s warranty page, and retailer listings at Northridge4x4 and Desert Rat. Where those sources disagree, we say so instead of picking the most flattering number. Every source is listed at the end of this article.
Quick verdict
The Kleinn Model 130 is the horn-only version of the triple-trumpet assembly that ships in Kleinn’s HK3 ProBlaster kit: three compact chrome trumpets on one bracket with Kleinn’s Model 307 12V solenoid already fitted, for $102.95. Kleinn rates it at 149.6 dB at 150 PSI and asks for only a 0.5-gallon tank, so it suits owners who already run onboard air and want a louder, sharper horn that fits behind a grille. We rate it 3.8/5. It loses points because the data around it is messy: Kleinn’s own page gives two different pressure ranges, retailers list different trumpet lengths, materials and dB figures, and no test distance is published. It’s a fair-value compact triple, but not one to buy on spec-sheet precision alone.
What it is
The Model 130 is a compact triple air horn, not a full-size train horn. Kleinn sorts its lineup into two families: the “Screamer” compact air horns (Models 102, 130 and 141) with 3.5-inch bells and a sharp, high-frequency blast meant to sound like an emergency vehicle, and the train horn series (500, 501, 502, 630 and others) with 6-7 inch bells for the deep locomotive rumble. The 130 is the three-trumpet member of the compact group, between the dual Model 102 and the quad Model 141.
Kleinn calls it a “balanced, mid-level entry” in the compact series. The pitch is simple: more presence than a factory horn without the size and mounting work of a large under-vehicle train horn rack. At about 14 inches long, 6 inches wide and 6.5 inches tall, it’s small enough for the spots Kleinn suggests, behind the grille or inside the engine bay.

The Model 130 is horn-only. There’s no compressor, tank, pressure switch or wiring in the box, so you need a working onboard air system before it will make a sound. If you don’t have one, Kleinn sells the same horn assembly as the HK3 complete kit, and our HK3 review covers that package. A black version, the Model 130-1, has an XCR 2.0 coated steel finish and lists at $92.95 with the same rated specs.

Two lines in that table need context. The 149.6 dB figure is Kleinn’s current rating at 150 PSI with no microphone distance given. Northridge4x4’s listing shows older, higher numbers: 152.9 dB at 150 PSI and 148.7 dB at 100 PSI, with a 160 PSI max input. We go with the manufacturer’s current figure and treat the retailer numbers as legacy data. Our guide to advertised vs. real-world decibels explains why a 3 dB gap between listings is less important than the missing test distance.
The pressure range is the other mismatch. Kleinn’s spec table says 120-150 PSI, but its “why choose” text says the horn works “reliably between 110 and 160 PSI,” and the system requirements note says 110-160 PSI. In practice, a common 150 PSI or 160 PSI cut-out system fits inside or very close to both ranges.
What’s in the box
According to Kleinn’s product page, the Model 130 ships with:
- Model 130 triple compact air horn assembly, chrome finish
- Model 307 Vortex 4 12V electronic air valve, pre-installed with a 1/4” fitting
- Small right-angle metal mounting bracket with hardware
What’s missing matters as much. There’s no compressor, tank, pressure switch, relay, horn button, wiring or airline. Kleinn’s quad Model 141 spec table lists 12 feet of 1/4” airline as included, but the Model 130 table lists only the airline input size, so plan on buying airline separately.
Pros
- Solenoid comes pre-installed, so you only plumb one 1/4” airline and run one 12V trigger wire
- Small footprint (about 14” x 6” x 6.5”) fits behind grilles and in engine bays where full-size train horns won’t
- Low 0.5-gallon minimum tank requirement works with modest existing air systems
- Kleinn publishes a dB rating with its test pressure, plus PSI, tank size and dimensions
- $102.95 for a three-trumpet metal horn with the valve included, consistent across Kleinn and retailers
- Same horn assembly Kleinn uses in its HK3 kit, so it’s a known part with replacement support
Cons
- No test distance disclosed for the 149.6 dB rating, and an older retailer listing shows 152.9 dB
- Kleinn’s own page gives two pressure ranges: 120-150 PSI and 110-160 PSI
- Retailers list different trumpet lengths and describe the trumpets as zinc alloy, not stainless steel
- Horn-only: needs a separate compressor, tank, wiring and airline
- Only a 1-year limited warranty
- Compact 3.5” bells produce a high-pitched, emergency-vehicle-style blast, not a deep locomotive tone
Alternatives
- Kleinn Model 141 (quad): the four-trumpet compact sibling at $134.95, rated 150.3 dB at 150 PSI with the same 307 valve and 0.5-gallon tank minimum. Its spec table also lists 12 feet of 1/4” airline as included.
- Kleinn Model 102 (dual): the cheaper two-trumpet option at $92.95, rated 149.1 dB at 150 PSI, in a longer, flatter 16.5” x 7.25” x 3.75” package that can fit thinner spaces.
- Kleinn Model 500 or Model 501 Warlock: Kleinn’s full-size triple train horns, rated 151.8 dB at 150 PSI, with the deeper locomotive tone the compact series doesn’t attempt. They cost more and need a bigger tank and more mounting space.
If you don’t have onboard air yet, the Kleinn HK3 bundles this same horn with a compressor, a 1-gallon tank and wiring. Our Kleinn vs HornBlasters guide compares the two brands.
Install / compatibility notes
The Model 130 is universal-fit and not vehicle-specific. Northridge4x4 notes that installation may need some modification. Here’s what Kleinn’s published requirements mean in practice:
- Air supply: Kleinn requires an onboard air system delivering 110-160 PSI (120-150 PSI per its spec table) and at least a 0.5-gallon tank. A bigger tank gives longer blasts. Our air tank size guide covers the sizing.
- Airline: the valve takes 1/4” OD airline. Route it away from exhaust and other heat sources. See air line routing and heat protection and air line size.
- Electrical: the Model 307 is a 12V electric valve. Trigger it through a relay from your horn button or factory horn circuit. Our relay wiring guide covers the setup, and Kleinn links its own air horn wiring diagram from the product page.
- Mounting: the single right-angle bracket makes this a one-location install. Point the trumpets level or slightly down so water can drain. See where to mount a train horn.
- Valve care: the solenoid is the most likely wear item. See our solenoid valve guide for symptoms and maintenance.
Kleinn also says the 130 works as a replacement part in existing Kleinn setups. If your HK3 horn assembly is damaged, this is the direct swap. Check your state’s horn rules before you install. Our guide on whether train horns are legal on cars is a good place to start.

The Model 130 is a good pick for owners who already run onboard air and want a louder, compact triple horn that hides behind a grille for about $100. Buyers without an air system should get the HK3 kit, and anyone who wants a deep locomotive tone should look at Kleinn's full-size 500 Series.
Frequently asked questions
Quick answers to the questions people ask most about this topic.
- How loud is the Kleinn Model 130?
- Kleinn rates it at 149.6 dB at 150 PSI but doesn't publish the test distance, so treat that as a manufacturer claim. An older Northridge4x4 listing shows 152.9 dB at 150 PSI and 148.7 dB at 100 PSI.
- Does the Kleinn Model 130 need a compressor and tank?
- Yes. It's horn-only, with the trumpets, a pre-installed Model 307 12V solenoid and a mounting bracket. Kleinn specifies onboard air at 110-160 PSI (120-150 PSI in its spec table) and at least a 0.5-gallon tank.
- What's the difference between the Model 130 and the Kleinn HK3?
- The HK3 is a complete kit built around the same Model 130 horn assembly. It adds a 130 PSI sealed compressor, a 1-gallon tank, a pressure switch and wiring for $439.95. The Model 130 alone is $102.95.
- Is the Model 130 a real train horn?
- No. Kleinn puts it in its compact 'Screamer' air horn series, which uses 3.5-inch bells for a sharp, emergency-vehicle-style blast. Kleinn's 500 Series train horns, with 6-7 inch bells, make the deep locomotive tone.
- What warranty does the Kleinn Model 130 have?
- Kleinn lists a 1-year limited warranty from the original purchase date.
