Install of Truck Air Horn Viair System in Chevy Silverado Truck

David from Fredericksburg, VA emailed pictures of his install of an Assured Performance Air Horn and Viair Air System he purchased from Assured Automotive Company.

Dual Trumpet Truck Air Horn Viair 150psi Kit

David installed the Dual Trumpet Truck Air Horn and 275c Viair Compressor 1 Gallon Air System in his 2010 Chevy Silverado 1500 Crew Cab 4×4.

Assured Automotive Company sell Train Air Horns as well as Air horns for Trucks and Cars.

The first thing that was installed was the one gallon Viair Air Tank.

The Viair air tank was installed in auxiliary battery tray behind the headlight.

Using the exiting holes, the tank mounted perfectly with ease.

The Viair 275c Compressor was mounted behind the front driver side headlight near the tank.

The Viair Compressor is behind the splash guard and is securely mounted using the 3 of the required 4 bolts, with 2 addtional holes needed to be drilled.

Because the compressor is basically mounted to a body panel and the frame, you can hear and feel the compressor when it runs.

David states that the sound and vibration of compressor in cab is tolerable and definitely can be lived with.

Now for the fun part, installing the Assured Performance ACHRSK-106 Truck Horn.

You can see the backs of the horns on the right side of the picture.

The install of the horns were quick and clean.  David mounted the horn vertically behind  the grill, near the Viair compressor.

Two holes needed to be drill in the grill to mount the air horn bracket to.

The decision to face the horns vertically, with the trumpet opening facing downward is a great decision.

This doesn’t allow any moisture from rain or snow to accumulate in the trumpets or in the diaphragm housings.

All horns should be mounted at a downward angle as much as possible.

Once the grill was reinstalled everything is well hidden from the outside of the Silverado.

From the inside the engine compartment the only thing that is really visible is the Viair air tank.

That is what we call a super clean install.

The included pressure switch and relay was wired in the engine compartment near the fuse box.

The trigger wire for the relay, the wire for the horn solenoid and some quarter inch tubing for the gauge was feed through the cabs firewall.

A hole was drilled near the brake booster and reservoir.

Custom Wiring Install of Truck Air Horn

After the tubing for the gauge and the relay trigger wire was ran into the cab, it was feed into the Chevy Silverado’s center console.

Another wire from under the dash that was an ignition source was also ran to the console.  These are only trigger wires, so installers can use thin wire like 16 gauge.

The two wire were connected to the switch in the gauge panel.

The tubing was plumbed to the gauge with the included compression fitting.

The wire that was feed from the horn solenoid was ran under the dash to a SPDT switch so user can switch from OE horn to Air Horn.

When steering wheel horn switch (OE Switch) is pressed, it will now sound the air horns.


David did a great job installing this horn.  He stated his friends are envious of him.

We are confident that David will be back when he needs another Air Horn for Truck

2009 Porsche Cayenne GTS-Air Horn System Installed

Jon H. from Virginia sent us some pics and info of his 2009 Porsche Cayenne GTS six speed with an Assured Performance Horn and Viair Air System

Jon purchase our 140db Dual Trumpet Truck Air Horn Kit with the Viair 400c Compressor and 2.5 gallon Tank Kit.

The truck horns went in behind front Right fender liner without much problem.

Left side was too crowded to use.

As you can see the horns are facing forward for the ultimate sound.

The Viair Tank, pump and controls went into Left Rear Quarter panel storage area.

We ran 40A line from battery, and relay current from the 12v outlet in photo. Controlled by steering wheel Horn button.

The pump is quite loud attached to the inner fender, but is ON so seldom that it is not a problem.

We needed additional hi pressure hose, so used some 150# truck brake line hose. It is more pliable and easier to install.

The kit was complete and the instructions were excellent. Installation took 12 hours.

It is of course VERY loud. The only thing I would change is someday perhaps to a lower note. I am looking for ‘Ocean Liner’ sound.

“Highly recommended. Thanks”

Assured Automotive Company Thanks Jon for the pics and info!!

EdzGarage Big Rig Air Horn Install Videos

Ed from EdzGarge posted a couple YouTube videos about an Assured Automotive Big Rig Dual Horn Kit with a VIAIR 20005 on board air system.

Ed’s son got this kit for his Dodge Ram 2500 pickup truck.  Ed relays to us that “My son really loves these horns… he can’t get the smile off his face! “.

The first video is the install of the kit in the his Dodge ram.


As impressive as the first video is, the second video is the most fun.  Ed did a “Sound Check” of the horn kit.


The kit that Ed purchased from Assured Automotive Company is a pair of 152db single trumpet air horns. Each horn is nearly 25 inches long and have a rectangle outlets which includes a “snow shields”.  The horns include air solenoids(electric valves).  These horns are designed to be roof mounted.  They have a mount on the rear of the diaphragm housing and an adjustable front mount.

The air system is a VIAIR 20005 kit which has a 2 gallon air tank and a 150psi VIAIR 30% Duty compressor.  The kit includes all mounting hardware, air tubing, fitting.  All that is not supplied is automotive wire and relay(optional).  This kit can supply air for horns, suspension bags, air lockers, and some air tools.

Ed did a great job on his videos and we appreciate the hard work he put into them.

If you have a video of installing or an installed Assured Automotive product, please forward it onto us.  We would love to share on this Customer Photo Blog.

Thanks Again Ed!!
