ARB air recommendations

I have decided to go ahead with my front and rear ARB set up after weeks of debate. I have had no luck with rancho air lines and leaking airbags in the past. I was really attracted to the Eaton e-lockers but Northridge 4X4 really pushed for the ARB so the next decision is the air source.

I really like the idea of an on board tank and the ability to fill tires and run a few tools in an emergency. Has anyone done this effectively without leaks? Is there a solution to do this for under $300? What regulators are you using that work for the ARB?

Done properly with teflon tape in the joints, you'll have no air leaks. Don't let anyone talk you into ARB's heavier-duty air lines, you need to stick with the standard air lines. Even ARB advises against the heavy-duty air lines and says to use the standard air lines for reasons explained in their FAQ... basically to avoid damaging hard or impossible to repair while on the trail. The standard duty air lines will just snap if they get snagged, producing a break that can be repaired in ten seconds with their splice-repair kit, not so with their heavier duty air lines that will rip out other fittings if they get snagged. But just properly routing the air lines will prevent this theoretical issue.

Leak-wise, I had a York compressor-based OBA system that was more complex and had more lines & fittings than an ARB air system has and it would hold air for literally (!) months. Proper assembly and installation will assure a leak-free system.

I'm not sure if you're planning to use the ARB compressor but here's a good working schematic for if you are considering other sources of air.

Personally, I'd go with a separate OBA system like VIAIR to run tools and fill tires, and get a dedicated compressor for the lockers - the one ARB sells is ideal for this purpose, as it's made to integrate with the lockers. They also have the heavy duty version, which can fill tires as well.

That's the best advice right there, I meant to include that above. Keeping your air sources for the ARB lockers and refilling your tires completely separate is the best way to keep everything as reliable as possible.

I went through a similar process, only I was interested in OX lockers. After speaking with a few vendors, they definitely convinced me that ARBs are the way.

Yes, there are many people running OBA set ups.

I suggest you look into a york style compressor. They move enough air to run air tools, fill up tires (fast), etc. ::Kilby Enterprises::

There is always Viair: VIAIR Corporation - 12 & 24 Volt Air Compressors

You can piece together kits, run C02 tanks, you just about have endless options.
Just do a search for "On Board Air" or OBA

Thanks guys, JB looks like you put many hours of thought in to that system.
I may just go with the $130 ARB system and forget about it and in time build a tank system that if it leaks a bit there is no harm.
WOW I wish I recived this much help so quickly with my gear patterns a few weeks ago.

I did, I am just thoroughly exhausted from the work it took. Blood, sweat, and tears. I must have spent all of 15-20 seconds finding that schematic in my bookmarks I copied from someone else years ago and posting it up for you.

How long will these ARB o-rings last? Are these something I will need to replace or service every few years, I know keeping rubber parts hydrated is key. I was told to use some vasaline on the rubber o-rings before I install. Can someone back that claim?

I'm not 100% sure but I believe that Vaseline, a petroleum-based lubricant, will attack the type of rubber used for those o-rings. I would use nothing more exotic than a common silicone o-ring lube.

Get the mini compressor. Install it and forget it. Once you discover the simplicity that ARB delivers to you in the form of their plug and play harness and easy to run and connect air lines, you will be kicking yourself for ever considering any other option for activating the lockers.

Another bit of advice- It's great to plan for emergencies and use that to justify all manner of things you can bolt on, carry around and stack into your rig. After a few years of doing so, you will wake up one day and figure out that all that crap you're doing for emergencies pretty much becomes a self fulfilling prophecy because all the weight you add transforms your rig into a lumbering beast on the trail and highway.

Vaseline will most definitely decompose o-rings. Dow 33 is good to use on o-rings, or any form of lubricant designed for high end paintball markers.

Also go easy on the teflon tape or use blue loctite on the connections. Little pieces of teflon tape can wreak havoc on a solenoid.

Thanks all ordered the ARB for the Dana 30 HP + the 30spline axles, also the ARB for the rear Dana 44 and decided on the small ARB compressor kit. Im sure there will be questions to come, my nights will be busy.

The Puma works well for my ARB's, tools and tires...

Yah that would work but then I guess you're the type that likes listening to the sound of your compressor inside your rig.

I can run a full day on the trail with Puma tank supplying air to the ARB's without the compressor kicking on. When it is running, it's 65 db...
