Air Werkz under the jeep mount with dual compressors with air tank

I am going to do a review and picture install of the newly released on board air system from Air Werkz (www.airwerkz.com)

This system consists of a 3 gal. Air tank, and either 1 or 2 VIAIR 400C compressors, and all the fittings and hoses to install it. The unique thing about this new kit it's that it comes with a newly designed mounting system that places all the components under the jeep. It mounts between the drive shaft and the exhaust resonator and attaches to the frame mount of the Evap resivor and the forward cross member.

Additional options are available like air gauge, adapter fitting for SPod, hoses etc.


The install is relatively simple and only requires drilling one hole for mounting the system, one to mount the Q/C air fitting and basic wrenches. However plan on a good 1/2 day + to complete the installation.

So lets get started.


The air tank is well made with 2 ports on both ends and a drain port on the bottom. As it sits in the picture on my bench, the tank is actually upside down

I opted for the dual 400C compressors. They are very nice and standard Viair quality. The come with stainless braided output lines on the compressors

And this the heart and soul of the system, the mounting bracket. As it sets on the bench, you are looking at the top side of the mount, and the side that is closest to the muffler.

The kit comes with a 6 port manifold, 4 center ports and one on each end. Plenty of room to plumb what ever you need.

And lastly the fittings for installing all the plumbing.



Now lets start putting everything together.

Before you start mounting all the components to the mounting bracket, you must first test fit it under the jeep and DRILL one mounting hole in frame crossmember.

The rear of the mount goes between the evap canister skid plate and the frame. You will re use the 2 factory bolts to mount it. Do not tighten the bolts at this time as you will need to align the front mounting holes.

The one side of the front mounting plate will line up with a factory hole in the front crossmember.





The other side will need to be drilled thru the crossmember as shown above.

Once the hole is drilled, you can remove the mounting bracket and proceed to the work bench so you can assemble all of the components.

The manifold attaches to the top center of the bracket

The fittings go right in, you use a couple of plugs for the extra holes in the manifold

Next you mount the compressors, if you are only using 1 would mount it in the forward location

The compressors look pretty bad A5S in there. From this view, the air tank will go on next.
This is the muffler side of the mounting bracket

This with the air tank mounted. Prior to mounting the tank you will need to install the air intake line to the compressor(s)

At this point you will install the tank drain valve on the bottom, the end tank fittings and connect the hoses to the tanks.

At this point I deviated from the standard install. I added a y adapter to the output of the tank so that I could run an Air Chuck to both sides of the jeep.

the kit comes with 1/4" an 3/8" air hose. The 1/4 is for the air lines and to run to a gauge. The 3/8" is for the intake on the air compressors. I chose to run 3/8 hose for my air lines and air intake.

Also you will need to mount the power relay and wire the compressors at this time.

Ok now that everything mounted to the bracket, get a friend to help hold it and install the system.

The assembled system is heavy and difficult to hold for one person.

This is what it looks like mounted, looking from driver to passenger side

This from passenger to driver side

This from the front of the drive shaft

And this is looking at the rear by the evap canister.





So I ran the air intake line to a "T" and then drilled a single hole into the driver side rear floor board and ran the filter behind the carpet. I did because I wanted to reduce the number of hoses running into the jeep. Travis from Air Werkz said that VIAIR recommends each compressor has its own intake and filter. That said I have worked with vacuum and pressure systems for a long time and the 2 ft of single hose Should not affect intake volume at all.

The other hose pictured running into the jeep is the line for the SPod air gauge.

And the red wire is the activation wire also running to the SPod.

The SPod air line (blue) is 1/8" and the Air Werkz (black) is 1/4 so you will need an adapter. If you do not use the 1/4" line out of the air tank, then you can use the 1/8-1/4 adapter that is supplied with the kit. If not you need to specify that you an SPod when your order and get an extra adapter.

After some Careful thinking and measuring I decide to mount the Air Chucks on the inside of the rear wheel wells on both sides. In the location I put them the tires will not hit them. Also I will have a little cover that will go over the fitting to keep mud and dirt out.

Here is a close up.

And finally, that battery connection. The kit does not come with power wire or the breaker to run from the battery to the unit. You will need about 7' of 6-8 gauge wire and a 40-50 amp breaker (as shown). You can NOT use a standard fuse on this system. When both compressors start the amperage spoke is so high that it will pop a glass or blade fuse every time if there is air in the tank.



This is a great system, it runs to 150psi in no time and fills the tank then shuts off. I have not had a chance to get out and air down yet but I will report back with my findings as soon as I do.

Love the setup, nice and clean, but I'm having trouble finding this exact system on their site... I have found the one that goes in the engine compartment but not this one. If you could provide a link that would be great.

I see the compressors are protected by a plate but it looks like the tanks pretty exposed. I really like this system but I think I will go with the compressors and try to mount the tank after I relocate my muffler. That way I can add a skid plate for it.

Do you air down your tires when you go offroad?

nicely done. i was planning to do an onboard system but during my last wheeling trip, the gas station air compressor failed on my buddy and we had to drive to another gas station...luckily it was across the street.

I needed an air compressor sooner than later...so i opted for the viair 400p which i found brand new on cl for 150.

great write up btw.

I'm interested in this kit, and I was wondering how it has held up for those that are using it? How has it handled the elements?

I end up getting the Dominion Offroad kit from EAD Offroad, the pump is mounted to the brake booster and the air chucks are inside the footwells, I did also opt for the external air chuck that I have mounted behind the front bumper.
