2010 Chevy Silverado Crew Cab 4x4

Added the 1 gallon ViAir tank on the driver’s side in front of the fuse/relay box. It[FONT=Courier New] fit perfect. Used existing holes in the tank bracket and tray.[/FONT]

[FONT=Courier New]
[FONT=Courier New]Mounted the ViAir 275C compressor on the diver’s side grille / headlight support bracket. [/FONT][FONT=Courier New][FONT=Courier New]Pressure switch is located under the compressor. [/FONT][/FONT]Was able to use 3 of the 4 required bolts. Had to drill two holes. When the compressor kicks on, you can hear and feel it… But nothing too bad. Splash guard covering compressor. (does not touch)

Horns were mounted vertically on the grille. Near the compressor. Had to drill 2 holes in grille to mount horns.
[FONT=Courier New]Horns seen from the front. Behind the grille. Once it is all back together. The tank is the only real visible item under the hood.[/FONT]

Drilled hole in firewall to run lines and wires to switches and gauge in the cab. This is the starter hole near the brake booster. (the compressor intake is also in the cab) [/FONT]SPDT switch to be able to switch between OEM horn or air horn. Used tan wire (-)(the correct 1 of the 3 in the same area under dash near steering column). OEM horns are 12v(+) and the air horns are wired 12v(+). Each ran to outer prongs of the switch. The center prong is the ground to the OEM horn button. OEM horn is a negative trigger.

Nice looked under the hood of my dads 08 never noticed that little tray,he’s getting the shockers sometime this year haha

Nice work! You can never go wrong with the viair tanks :slight_smile:

Looks good! Sorry if I missed it, but are they Shockers? They almost look like something else in the pic through the grill. How much honk time do you get out of that tank?

Thanks for the wiring tips. Couple threads/posts lately helping me out w/ my GMC.

Nice setup man! What are you using to power the compressor?

Real nice setup, ill admit i honestly cant find the compressor in the 3rd picture. That is what the picture is right?? Haha

Here is the compressor mounted. (the previous compressor pic was just the location, compressor wasn’t mounted yet)

I get power (fused) from the battery to the pressure switch, then from the pressure switch to the compressor.

I also ran a ground from the battery over to the switch and compressor for a good ground.

I haven’t timed my honk time yet… but I have not had any issues getting folks attention.

The set up was a gift, I was told they were shockers but while doing research for the install, I noticed the horns are not. It is a Viair tank, compressor and switch but I have no clue what horns they are. They are a dual trumpet and I can’t see any markings.

One of the guys at work heard me playing around with them one day and came out… he has the shockers (so he says) and the horns look different… but no real noticeable difference in “loudness”. Different tone…but both sounded great!

Maybe it’s a Rocker horn kit, which is the two smaller trumpets out of the Shockers. Did the horns have any markings?
