Product Description

Give any truck the powerful sound of a train air horn. The SIBERIAN EXPRESS has been engineered with the latest technology using reinforced ABS plastic. The sound produced by the three trumpets is incredible. Using reinforced ABS plastic decreases the overall weight by eleven and half pounds – (11.5 lbs.) The Siberian Express weight is two-thirds less compared to the same type train horn that is metal. The reduced weight makes installation easier, ensures less vibration and eliminates the need for extra support brackets to prevent damage to the horn when driving on rough roads. The trumpets are finished with an attractive semi-gloss black finish and the mounting base is painted silver. The SIBERIAN EXPRESS requires an on-board air system with a minimum of two (2) gallon storage tank, (recommended Wolo on-board air system Model 840). Kit comes with all mounting hardware, 10 feet of 1/4” O.D. nylon high-pressure hose, and a heavy-duty 12-volt electric solenoid. H orn size: L 16-1/2 in. x W 14-3/4 in. x H 11 in - 152 Decibels – 307/347/440 Hz

Great horn
By Hunter
I installed this horn on my truck and it is LOUD I've got a friend that has a WOLO bad boy on his truck and it dosen't even come close to how loud this one is. took it to a 4 story parking garage and set off all the alarms on the first floor and set off all the aftermarket alarms on the other 3 floors after hitting it for 2 seconds.

LOUD & BIG
By Rattler
First off these are BIG ( pics to follow ) and they are LOUD and have a GREAT SOUND, I have not put them in yet ( going to be a bit of a project due to the size of these ) but I HAD TO HEAR THEM when they got here lol which BTW Amazon REALLY came through on this one ordered them and they showed up in TWO DAYS and on a Saturday to boot.

Couldn't wait to hear them so I temporarily hooked these up to my 60gal air compressor in my garage with a hose run to them OUTSIDE ( DON'T TRY THESE INDOORS, THEY WILL HURT YOU ) to test it out and they live up to the hype LOVE HEARING THE ECHO OF A TRAIN HORN

Are they AS LOUD as a REAL train horn? NO but they are close and at 1/10 the cost they are just AWESOME, loud enough to let EVERYONE within a mile or two know you are there for SURE. And even though I did warn my family as to what was coming they still jumped, dogs ran off, and even the horses said we are out of here lol

For the money these are just AWESOME hope they last, can't wait to get them installed,it appears that the included bracket can be removed so mounting options are "adaptable" the only reason for the one missing star is the 1/4" input on these my system is 1/2" - other than that NO COMPLAINTS

PICS and a follow up after install

UPDATED INFO FROM WOLO tech support - I am running a 150psi system and was curious if this was too much for this horn? I was right. This morning I called Wolo's tech support and found out that the recommended system pressure for this horn is 80-110psi. I asked what the MAX pressure this horn should receive and was told 110psi, so I just had to order a 1/2" regulator to be able to turn down the pressure to this horn on my system.

Another expense, but having a regulator on the horn line will allow me to adjust pressure for a good sound and prevent risking damage to the horns - I guess lol

TWO MONTHS of use update - They still s ound great ( at times almost too loud lol ) they will scare the **ap out of people even when they KNOW that they are there. I did kind of find out the hard way that these WILL SOUND on low pressure - my gauge read ZERO so there was probably less than 10psi on my system but when I pressed the horn they still sounded off LOL sounded pretty pitiful, but still sounded off. Can't wait to be able to put my Graham White valve in and make these sound like they are truly supposed to.

excellent sound
By J. Phillips
These horns have been on my truck over a year now and still sound excellent, they are very loud and seem to be quite durable.
