New Overland member and new Jeep JLU owner. I’m looking into getting an ARB Air Compressor to inflate my tires. Does anyone have experience with that brand and mounting options on the Jeep.
Thanks

Arb is probably the most known compressor. Many people use the dual compressor for its compactness and speed.
Viair is a good alternative, but bigger and has a sizable tank.
I can't speak to mounting options as there are many brands. At the end of the day, it's a piece of bent metal with possibly a coat, and a few holes.

Thanks for the info. I have the same concern for getting it dirty and wearing out quicker if I mount it under the hood.

I think it really depends on what you want to do. The way I see the differences between a few of the models of Viair vs ARB:
Smaller Viair units (without the external tank), are the same as ARB. Viair 400P, or 300P, are smaller units, and then there's even smaller units but probably can't fill up to what you need.
ARB has the dual unit, which is just 2 units connected internally and faster to fill. $550 or so tho.
Bigger Viair units such as Viair 200 or the 10007 unit have an external tank, and you'll always have air in the tank to use. This will help with faster fill, and you can also use pneumatic tools too with it (to some extent). This takes up 3x the space tho with a tank.
With all that said, I have a 85P for my 33 inch tires and I can only fill up to about 33PSI. It is slow, and hasn't shut down on me yet, but I am looking to upgrade soon to possibly an ARB dual air compressor and keep it in the engine bay.

I run stock sized tires (235/75R15 not exactly stock but pretty close) and run the largest VIAIR they have that still plugs into the lighter port. I can be aired back up and ready to roll in about 10 minutes. In the past I ran CO2 onboard and while that's the fastest I've used it takes up a decent amount of space and once you are out there's no way to refill without access to a welding supply store or some other place that refills or exchanges cylinders.

I agree, the ammount of electric tools that run on lithium batteries makes running an air tank pretty much obsolete. And you can recharge on the go. I dont know of any power tank that can run a impact and a chainsaw.

I have had my Smittybuilt compressor for a week now. They fill up my 35's just fine. take about 15 minutes for all 4 tires however. I really like it so far.
Enthusiast III
For $130.00 bucks, as long as you watch how hot the air lead gets, it seems like a solid deal for as often as I use it.
One quick tip if you're filling up tires one at a time, pull the valve core. I have basically 33's and it takes like 2-3 minutes a tire to go from 18 to 35 psi when I pull the core.
It helps the compressor not work as hard as well
Sorry if I'm the dumbest kid in school but how does this work? Do you over-inflate and then try to get the valve core back in quickly?
Enthusiast III
No, you got it exactly. I have a core puller tool like this one here. I use it for my mountain bike all the time and is really easy to use compared to the ones that come with the ARB air down kit. Typically I will go 1 or 2 psi over my desired pressure and then pull off the compressor connection and put the core back in in less than a second. The best part about this tool is it "holds" the core really well so you don't have to fumble with it trying to get it back in.

Chainsaw no. Impact gun hell yeah. When my last compressor died I ran all of my shop air tools of of my 20 lb CO2 tank for a while. NOT a powertank. No way I would spend the money they want for a gussied up CO2 setup. A 20lb tank will air up quite a few tires, and run an impact gun for quite a while, same for an air ratchet.
You can put together a decent CO2 setup with a 10 or 20 lb tank for pretty cheap now. Look for someone getting out of the brewing or kegerator game on FB Marketplace and pick up a used cylinder (make sure the hydro test date is good). Should be about 40 or 50 dollars, another 70 for a high flow regulator off of EBAY, then a decent 25 foot rubber air hose. Then when you generic CO2 tank runs low you just go to a welding supply store and exchange it for 20 dollars.

Love my ARB CKMA24 on board. Super handy! For larger tires than 33’s the dual compressor is more capable. As for mounts, check out Rago Fabrications options. They also make a system called the “wifey air” system. Using a manifold you can air up all 4 tires at the same time. So your wifey doesn’t have to wait 20 min while you air up lol.
